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.
This function is similar to g_time_zone_find_interval(), with the
difference that it always succeeds (by making the adjustments
described below).
In any of the cases where g_time_zone_find_interval() succeeds then
this function returns the same value, without modifying time_.
This function may, however, modify time_ in order to deal with
non-existent times. If the non-existent local time_ of 02:30 were
requested on March 14th 2010 in Toronto then this function would
adjust time_ to be 03:00 and return the interval containing the
adjusted time.
the GLib.TimeType of time_
a pointer to a number of seconds since January 1, 1970
the interval containing time_, never -1
Finds an interval within tz that corresponds to the given time_.
The meaning of time_ depends on type.
If type is GLib.TimeType.UNIVERSAL then this function will always
succeed (since universal time is monotonic and continuous).
Otherwise time_ is treated as local time. The distinction between
GLib.TimeType.STANDARD and GLib.TimeType.DAYLIGHT is ignored except in
the case that the given time_ is ambiguous. In Toronto, for example,
01:30 on November 7th 2010 occurred twice (once inside of daylight
savings time and the next, an hour later, outside of daylight savings
time). In this case, the different value of type would result in a
different interval being returned.
It is still possible for this function to fail. In Toronto, for example, 02:00 on March 14th 2010 does not exist (due to the leap forward to begin daylight savings time). -1 is returned in that case.
the GLib.TimeType of time_
a number of seconds since January 1, 1970
the interval containing time_, or -1 in case of failure
Determines the time zone abbreviation to be used during a particular
interval of time in the time zone tz.
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.

the time zone abbreviation, which belongs to tz
Get the identifier of this GLib.TimeZone, as passed to g_time_zone_new().
If the identifier passed at construction time was not recognised, UTC will
be returned. If it was null, the identifier of the local timezone at
construction time will be returned.
The identifier will be returned in the same format as provided at construction time: if provided as a time offset, that will be returned by this function.
identifier for this timezone
Determines the offset to UTC in effect during a particular interval
of time in the time zone tz.
The offset is the number of seconds that you add to UTC time to
arrive at local time for tz (ie: negative numbers for time zones
west of GMT, positive numbers for east).
an interval within the timezone
the number of seconds that should be added to UTC to get the local time in tz
Determines if daylight savings time is in effect during a particular
interval of time in the time zone tz.
an interval within the timezone
true if daylight savings time is in effect
Decreases the reference count on tz.

A GLib.TimeZone represents a time zone, at no particular point in time.
The GLib.TimeZone struct is refcounted and immutable.
Each time zone has an identifier (for example, ‘Europe/London’) which is platform dependent. See GLib.TimeZone.new for information on the identifier formats. The identifier of a time zone can be retrieved using GLib.TimeZone.get_identifier.
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.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.
