glib.time_zone
Module for [TimeZone] class
Types 1
A [glib.time_zone.TimeZone] represents a time zone, at no particular point in time.
The [glib.time_zone.TimeZone] struct is refcounted and immutable.
Each time zone has an identifier (for example, ‘Europe/London’) which is platform dependent. See [glib.time_zone.TimeZone.new_] for information on the identifier formats. The identifier of a time zone can be retrieved using [glib.time_zone.TimeZone.getIdentifier].
A time zone contains a number of intervals. Each interval has an abbreviation to describe it (for example, ‘PDT’), an offset to UTC and a flag indicating if the daylight savings time is in effect during that interval. A time zone always has at least one interval — interval 0. Note that interval abbreviations are not the same as time zone identifiers (apart from ‘UTC’), and cannot be passed to [glib.time_zone.TimeZone.new_].
Every UTC time is contained within exactly one interval, but a given local time may be contained within zero, one or two intervals (due to incontinuities associated with daylight savings time).
An interval may refer to a specific period of time (eg: the duration of daylight savings time during 2010) or it may refer to many periods of time that share the same properties (eg: all periods of daylight savings time). It is also possible (usually for political reasons) that some properties (like the abbreviation) change between intervals without other properties changing.
glib.time_zone.TimeZone newIdentifier(string identifier = null)Creates a #GTimeZone corresponding to identifier. If identifier cannot be parsed or loaded, null is returned.glib.time_zone.TimeZone newLocal()Creates a #GTimeZone corresponding to local time. The local time zone may change between invocations to this function; for example, if the system administrator changes it.glib.time_zone.TimeZone newOffset(int seconds)Creates a #GTimeZone corresponding to the given constant offset from UTC, in seconds.glib.time_zone.TimeZone newUtc()Creates a #GTimeZone corresponding to UTC.int adjustTime(glib.types.TimeType type, ref long time)Finds an interval within tz that corresponds to the given time, possibly adjusting time if required to fit into an interval. The meaning of time_ depends on type.int findInterval(glib.types.TimeType type, long time)Finds an interval within tz that corresponds to the given time. The meaning of time depends on type.string getAbbreviation(int interval)Determines the time zone abbreviation to be used during a particular interval of time in the time zone tz.string getIdentifier()Get the identifier of this #GTimeZone, as passed to [glib.timezone.TimeZone.new]. If the identifier passed at construction time was not recognised, `UTC` will be returned. If it was null, the ident...int getOffset(int interval)Determines the offset to UTC in effect during a particular interval of time in the time zone tz.bool isDst(int interval)Determines if daylight savings time is in effect during a particular interval of time in the time zone tz.
