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