Details

class GLib.DateTime

GDateTime is an opaque structure whose members cannot be accessed directly.

New in version 2.26.

classmethod compare(dt1, dt2)[source]
Parameters:
Returns:

-1, 0 or 1 if dt1 is less than, equal to or greater than dt2.

Return type:

int

A comparison function for GLib.DateTimes that is suitable as a GLib.CompareFunc. Both GLib.DateTimes must be non-None.

New in version 2.26.

classmethod equal(dt1, dt2)[source]
Parameters:
Returns:

True if dt1 and dt2 are equal

Return type:

bool

Checks to see if dt1 and dt2 are equal.

Equal here means that they represent the same moment after converting them to the same time zone.

New in version 2.26.

classmethod hash(datetime)[source]
Parameters:datetime (object) – a GLib.DateTime
Returns:a int containing the hash
Return type:int

Hashes datetime into a int, suitable for use within GLib.HashTable.

New in version 2.26.

classmethod new(tz, year, month, day, hour, minute, seconds)[source]
Parameters:
  • tz (GLib.TimeZone) – a GLib.TimeZone
  • year (int) – the year component of the date
  • month (int) – the month component of the date
  • day (int) – the day component of the date
  • hour (int) – the hour component of the date
  • minute (int) – the minute component of the date
  • seconds (float) – the number of seconds past the minute
Returns:

a new GLib.DateTime, or None

Return type:

GLib.DateTime or None

Creates a new GLib.DateTime corresponding to the given date and time in the time zone tz.

The year must be between 1 and 9999, month between 1 and 12 and day between 1 and 28, 29, 30 or 31 depending on the month and the year.

hour must be between 0 and 23 and minute must be between 0 and 59.

seconds must be at least 0.0 and must be strictly less than 60.0. It will be rounded down to the nearest microsecond.

If the given time is not representable in the given time zone (for example, 02:30 on March 14th 2010 in Toronto, due to daylight savings time) then the time will be rounded up to the nearest existing time (in this case, 03:00). If this matters to you then you should verify the return value for containing the same as the numbers you gave.

In the case that the given time is ambiguous in the given time zone (for example, 01:30 on November 7th 2010 in Toronto, due to daylight savings time) then the time falling within standard (ie: non-daylight) time is taken.

It not considered a programmer error for the values to this function to be out of range, but in the case that they are, the function will return None.

You should release the return value by calling GLib.DateTime.unref() when you are done with it.

New in version 2.26.

classmethod new_from_iso8601(text, default_tz)[source]
Parameters:
Returns:

a new GLib.DateTime, or None

Return type:

GLib.DateTime or None

Creates a GLib.DateTime corresponding to the given ISO 8601 formatted string text. ISO 8601 strings of the form <date><sep><time><tz> are supported, with some extensions from RFC 3339 as mentioned below.

Note that as GLib.DateTime “is oblivious to leap seconds”, leap seconds information in an ISO-8601 string will be ignored, so a 23:59:60 time would be parsed as 23:59:59.

<sep> is the separator and can be either ‘T’, ‘t’ or ‘ ‘. The latter two separators are an extension from RFC 3339.

<date> is in the form:

  • YYYY-MM-DD - Year/month/day, e.g. 2016-08-24.
  • YYYYMMDD - Same as above without dividers.
  • YYYY-DDD - Ordinal day where DDD is from 001 to 366, e.g. 2016-237.
  • YYYYDDD - Same as above without dividers.
  • YYYY-Www-D - Week day where ww is from 01 to 52 and D from 1-7, e.g. 2016-W34-3.
  • YYYYWwwD - Same as above without dividers.

<time> is in the form:

  • hh:mm:ss(.sss) - Hours, minutes, seconds (subseconds), e.g. 22:10:42.123.
  • hhmmss(.sss) - Same as above without dividers.

<tz> is an optional timezone suffix of the form:

  • Z - UTC.
  • +hh:mm or -hh:mm - Offset from UTC in hours and minutes, e.g. +12:00.
  • +hh or -hh - Offset from UTC in hours, e.g. +12.

If the timezone is not provided in text it must be provided in default_tz (this field is otherwise ignored).

This call can fail (returning None) if text is not a valid ISO 8601 formatted string.

You should release the return value by calling GLib.DateTime.unref() when you are done with it.

New in version 2.56.

classmethod new_from_timeval_local(tv)[source]
Parameters:tv (GLib.TimeVal) – a GLib.TimeVal
Returns:a new GLib.DateTime, or None
Return type:GLib.DateTime or None

Creates a GLib.DateTime corresponding to the given GLib.TimeVal tv in the local time zone.

The time contained in a GLib.TimeVal is always stored in the form of seconds elapsed since 1970-01-01 00:00:00 UTC, regardless of the local time offset.

This call can fail (returning None) if tv represents a time outside of the supported range of GLib.DateTime.

You should release the return value by calling GLib.DateTime.unref() when you are done with it.

New in version 2.26.

Deprecated since version 2.62: GLib.TimeVal is not year-2038-safe. Use GLib.DateTime.new_from_unix_local() instead.

classmethod new_from_timeval_utc(tv)[source]
Parameters:tv (GLib.TimeVal) – a GLib.TimeVal
Returns:a new GLib.DateTime, or None
Return type:GLib.DateTime or None

Creates a GLib.DateTime corresponding to the given GLib.TimeVal tv in UTC.

The time contained in a GLib.TimeVal is always stored in the form of seconds elapsed since 1970-01-01 00:00:00 UTC.

This call can fail (returning None) if tv represents a time outside of the supported range of GLib.DateTime.

You should release the return value by calling GLib.DateTime.unref() when you are done with it.

New in version 2.26.

Deprecated since version 2.62: GLib.TimeVal is not year-2038-safe. Use GLib.DateTime.new_from_unix_utc() instead.

classmethod new_from_unix_local(t)[source]
Parameters:t (int) – the Unix time
Returns:a new GLib.DateTime, or None
Return type:GLib.DateTime or None

Creates a GLib.DateTime corresponding to the given Unix time t in the local time zone.

Unix time is the number of seconds that have elapsed since 1970-01-01 00:00:00 UTC, regardless of the local time offset.

This call can fail (returning None) if t represents a time outside of the supported range of GLib.DateTime.

You should release the return value by calling GLib.DateTime.unref() when you are done with it.

New in version 2.26.

classmethod new_from_unix_utc(t)[source]
Parameters:t (int) – the Unix time
Returns:a new GLib.DateTime, or None
Return type:GLib.DateTime or None

Creates a GLib.DateTime corresponding to the given Unix time t in UTC.

Unix time is the number of seconds that have elapsed since 1970-01-01 00:00:00 UTC.

difference(begin)[source]
Parameters:begin (GLib.DateTime) – a GLib.DateTime
Returns:the difference between the two GLib.DateTime, as a time span expressed in microseconds.
Return type:int

Calculates the difference in time between self and begin. The #GTimeSpan that is returned is effectively self - begin (ie: positive if the first parameter is larger).

New in version 2.26.

format(format)[source]
Parameters:format (str) – a valid UTF-8 string, containing the format for the GLib.DateTime
Returns:a newly allocated string formatted to the requested format or None in the case that there was an error (such as a format specifier not being supported in the current locale). The string should be freed with GLib.free().
Return type:str or None

Creates a newly allocated string representing the requested format.

The format strings understood by this function are a subset of the strftime() format language as specified by C99. The \%D, \%U and \%W conversions are not supported, nor is the ‘E’ modifier. The GNU extensions \%k, \%l, \%s and \%P are supported, however, as are the ‘0’, ‘_’ and ‘-‘ modifiers. The Python extension \%f is also supported.

In contrast to strftime(), this function always produces a UTF-8 string, regardless of the current locale. Note that the rendering of many formats is locale-dependent and may not match the strftime() output exactly.

The following format specifiers are supported:

  • \%a: the abbreviated weekday name according to the current locale
  • \%A: the full weekday name according to the current locale
  • \%b: the abbreviated month name according to the current locale
  • \%B: the full month name according to the current locale
  • \%c: the preferred date and time representation for the current locale
  • \%C: the century number (year/100) as a 2-digit integer (00-99)
  • \%d: the day of the month as a decimal number (range 01 to 31)
  • \%e: the day of the month as a decimal number (range 1 to 31)
  • \%F: equivalent to %Y-%m-%d (the ISO 8601 date format)
  • \%g: the last two digits of the ISO 8601 week-based year as a decimal number (00-99). This works well with \%V and \%u.
  • \%G: the ISO 8601 week-based year as a decimal number. This works well with \%V and \%u.
  • \%h: equivalent to \%b
  • \%H: the hour as a decimal number using a 24-hour clock (range 00 to 23)
  • \%I: the hour as a decimal number using a 12-hour clock (range 01 to 12)
  • \%j: the day of the year as a decimal number (range 001 to 366)
  • \%k: the hour (24-hour clock) as a decimal number (range 0 to 23); single digits are preceded by a blank
  • \%l: the hour (12-hour clock) as a decimal number (range 1 to 12); single digits are preceded by a blank
  • \%m: the month as a decimal number (range 01 to 12)
  • \%M: the minute as a decimal number (range 00 to 59)
  • \%f: the microsecond as a decimal number (range 000000 to 999999)
  • \%p: either “AM” or “PM” according to the given time value, or the corresponding strings for the current locale. Noon is treated as “PM” and midnight as “AM”. Use of this format specifier is discouraged, as many locales have no concept of AM/PM formatting. Use \%c or \%X instead.
  • \%P: like \%p but lowercase: “am” or “pm” or a corresponding string for the current locale. Use of this format specifier is discouraged, as many locales have no concept of AM/PM formatting. Use \%c or \%X instead.
  • \%r: the time in a.m. or p.m. notation. Use of this format specifier is discouraged, as many locales have no concept of AM/PM formatting. Use \%c or \%X instead.
  • \%R: the time in 24-hour notation (\%H:\%M)
  • \%s: the number of seconds since the Epoch, that is, since 1970-01-01 00:00:00 UTC
  • \%S: the second as a decimal number (range 00 to 60)
  • \%t: a tab character
  • \%T: the time in 24-hour notation with seconds (\%H:\%M:\%S)
  • \%u: the ISO 8601 standard day of the week as a decimal, range 1 to 7, Monday being 1. This works well with \%G and \%V.
  • \%V: the ISO 8601 standard week number of the current year as a decimal number, range 01 to 53, where week 1 is the first week that has at least 4 days in the new year. See GLib.DateTime.get_week_of_year(). This works well with \%G and \%u.
  • \%w: the day of the week as a decimal, range 0 to 6, Sunday being 0. This is not the ISO 8601 standard format – use \%u instead.
  • \%x: the preferred date representation for the current locale without the time
  • \%X: the preferred time representation for the current locale without the date
  • \%y: the year as a decimal number without the century
  • \%Y: the year as a decimal number including the century
  • \%z: the time zone as an offset from UTC (+hhmm)
  • \%:py:data::z<GLib.DateTime.props.z>: the time zone as an offset from UTC (+hh:mm). This is a gnulib strftime() extension. Since: 2.38
  • \%:py:func:::z<GLib.DateTime.signals.z>: the time zone as an offset from UTC (+hh:mm:py:data::ss<GLib.DateTime.props.ss>). This is a gnulib strftime() extension. Since: 2.38
  • \%:::z: the time zone as an offset from UTC, with : to necessary precision (e.g., -04, +05:30). This is a gnulib strftime() extension. Since: 2.38
  • \%Z: the time zone or name or abbreviation
  • \%\%: a literal \% character

Some conversion specifications can be modified by preceding the conversion specifier by one or more modifier characters. The following modifiers are supported for many of the numeric conversions:

  • O: Use alternative numeric symbols, if the current locale supports those.
  • _: Pad a numeric result with spaces. This overrides the default padding for the specifier.
  • -: Do not pad a numeric result. This overrides the default padding for the specifier.
  • 0: Pad a numeric result with zeros. This overrides the default padding for the specifier.

Additionally, when O is used with B, b, or h, it produces the alternative form of a month name. The alternative form should be used when the month name is used without a day number (e.g., standalone). It is required in some languages (Baltic, Slavic, Greek, and more) due to their grammatical rules. For other languages there is no difference. \%OB is a GNU and BSD strftime() extension expected to be added to the future POSIX specification, \%Ob and \%Oh are GNU strftime() extensions. Since: 2.56

New in version 2.26.

format_iso8601()[source]
Returns:a newly allocated string formatted in ISO 8601 format or None in the case that there was an error. The string should be freed with GLib.free().
Return type:str or None

Return type:float

Retrieves the number of seconds since the start of the last minute, including the fractional part.

New in version 2.26.

get_timezone()[source]
Returns:the time zone
Return type:GLib.TimeZone

Get the time zone for this self.

New in version 2.58.

get_timezone_abbreviation()[source]
Returns:the time zone abbreviation. The returned string is owned by the GLib.DateTime and it should not be modified or freed
Return type:str

Determines the time zone abbreviation to be used at the time and in the time zone of self.

For example, in Toronto this is currently “EST” during the winter months and “EDT” during the summer months when daylight savings time is in effect.

New in version 2.26.

get_utc_offset()[source]
Returns:the number of microseconds that should be added to UTC to get the local time
Return type:int

Determines the offset to UTC in effect at the time and in the time zone of self.

The offset is the number of microseconds that you add to UTC time to arrive at local time for the time zone (ie: negative numbers for time zones west of GMT, positive numbers for east).

If self represents UTC time, then the offset is always zero.

New in version 2.26.

get_week_numbering_year()[source]
Returns:the ISO 8601 week-numbering year for self
Return type:int

Returns the ISO 8601 week-numbering year in which the week containing self falls.

This function, taken together with GLib.DateTime.get_week_of_year() and GLib.DateTime.get_day_of_week() can be used to determine the full ISO week date on which self falls.

This is usually equal to the normal Gregorian year (as returned by GLib.DateTime.get_year()), except as detailed below:

For Thursday, the week-numbering year is always equal to the usual calendar year. For other days, the number is such that every day within a complete week (Monday to Sunday) is contained within the same week-numbering year.

For Monday, Tuesday and Wednesday occurring near the end of the year, this may mean that the week-numbering year is one greater than the calendar year (so that these days have the same week-numbering year as the Thursday occurring early in the next year).

For Friday, Saturday and Sunday occurring near the start of the year, this may mean that the week-numbering year is one less than the calendar year (so that these days have the same week-numbering year as the Thursday occurring late in the previous year).

An equivalent description is that the week-numbering year is equal to the calendar year containing the majority of the days in the current week (Monday to Sunday).

Note that January 1 0001 in the proleptic Gregorian calendar is a Monday, so this function never returns 0.

New in version 2.26.

get_week_of_year()[source]
Returns:the ISO 8601 week number for self.
Return type:int

Returns the ISO 8601 week number for the week containing self. The ISO 8601 week number is the same for every day of the week (from Moday through Sunday). That can produce some unusual results (described below).

The first week of the year is week 1. This is the week that contains the first Thursday of the year. Equivalently, this is the first week that has more than 4 of its days falling within the calendar year.

The value 0 is never returned by this function. Days contained within a year but occurring before the first ISO 8601 week of that year are considered as being contained in the last week of the previous year. Similarly, the final days of a calendar year may be considered as being part of the first ISO 8601 week of the next year if 4 or more days of that week are contained within the new year.

New in version 2.26.

Returns:the GLib.DateTime with the reference count increased
Return type:GLib.DateTime

Atomically increments the reference count of self by one.

New in version 2.26.

to_local()[source]
Returns:the newly created GLib.DateTime which should be freed with GLib.DateTime.unref(), or None
Return type:GLib.DateTime or None

Creates a new GLib.DateTime corresponding to the same instant in time as self, but in the local time zone.

This call is equivalent to calling GLib.DateTime.to_timezone() with the time zone returned by GLib.TimeZone.new_local().

New in version 2.26.

to_timeval(tv)[source]
Parameters:tv (GLib.TimeVal) – a GLib.TimeVal to modify
Returns:True if successful, else False
Return type:bool

Stores the instant in time that self represents into tv.

The time contained in a GLib.TimeVal is always stored in the form of seconds elapsed since 1970-01-01 00:00:00 UTC, regardless of the time zone associated with self.

On systems where ‘long’ is 32bit (ie: all 32bit systems and all Windows systems), a GLib.TimeVal is incapable of storing the entire range of values that GLib.DateTime is capable of expressing. On those systems, this function returns False to indicate that the time is out of range.

On systems where ‘long’ is 64bit, this function never fails.

New in version 2.26.

Deprecated since version 2.62: GLib.TimeVal is not year-2038-safe. Use GLib.DateTime.to_unix() instead.

to_timezone(tz)[source]
Parameters:tz (GLib.TimeZone) – the new GLib.TimeZone
Returns:the newly created GLib.DateTime which should be freed with GLib.DateTime.unref(), or None
Return type:GLib.DateTime or None

Create a new GLib.DateTime corresponding to the same instant in time as self, but in the time zone tz.

This call can fail in the case that the time goes out of bounds. For example, converting 0001-01-01 00:00:00 UTC to a time zone west of Greenwich will fail (due to the year 0 being out of range).

New in version 2.26.

to_unix()[source]
Returns:the Unix time corresponding to self
Return type:int

Gives the Unix time corresponding to self, rounding down to the nearest second.

Unix time is the number of seconds that have elapsed since 1970-01-01 00:00:00 UTC, regardless of the time zone associated with self.

New in version 2.26.

to_utc()[source]
Returns:the newly created GLib.DateTime which should be freed with GLib.DateTime.unref(), or None
Return type:GLib.DateTime or None

Creates a new GLib.DateTime corresponding to the same instant in time as self, but in UTC.

This call is equivalent to calling GLib.DateTime.to_timezone() with the time zone returned by GLib.TimeZone.new_utc().

New in version 2.26.

unref()[source]

Atomically decrements the reference count of self by one.

When the reference count reaches zero, the resources allocated by self are freed

New in version 2.26.
