    -- | Creates a t'GI.GLib.Structs.TimeZone.TimeZone' corresponding to /@identifier@/.

    -- /@identifier@/ can either be an RFC3339\/ISO 8601 time offset or
    -- something that would pass as a valid value for the @TZ@ environment
    -- variable (including 'P.Nothing').
    --
    -- In Windows, /@identifier@/ can also be the unlocalized name of a time
    -- zone for standard time, for example \"Pacific Standard Time\".
    --
    -- Valid RFC3339 time offsets are @\"Z\"@ (for UTC) or
    -- @\"±hh:mm\"@.  ISO 8601 additionally specifies
    -- @\"±hhmm\"@ and @\"±hh\"@.  Offsets are
    -- time values to be added to Coordinated Universal Time (UTC) to get
    -- the local time.
    --
    -- In UNIX, the @TZ@ environment variable typically corresponds
    -- to the name of a file in the zoneinfo database, an absolute path to a file
    -- somewhere else, or a string in
    -- \"std offset [dst [offset],start[\/time],end[\/time]]\" (POSIX) format.
    -- There  are  no spaces in the specification. The name of standard
    -- and daylight savings time zone must be three or more alphabetic
    -- characters. Offsets are time values to be added to local time to
    -- get Coordinated Universal Time (UTC) and should be
    -- @\"[±]hh[[:]mm[:ss]]\"@.  Dates are either
    -- @\"Jn\"@ (Julian day with n between 1 and 365, leap
    -- years not counted), @\"n\"@ (zero-based Julian day
    -- with n between 0 and 365) or @\"Mm.w.d\"@ (day d
    -- (0 \<= d \<= 6) of week w (1 \<= w \<= 5) of month m (1 \<= m \<= 12), day
    -- 0 is a Sunday).  Times are in local wall clock time, the default is
    -- 02:00:00.
    --
    -- In Windows, the \"tzn[+|–]hh[:mm[:ss]][dzn]\" format is used, but also
    -- accepts POSIX format.  The Windows format uses US rules for all time
    -- zones; daylight savings time is 60 minutes behind the standard time
    -- with date and time of change taken from Pacific Standard Time.
    -- Offsets are time values to be added to the local time to get
    -- Coordinated Universal Time (UTC).
    --
    -- 'GI.GLib.Structs.TimeZone.timeZoneNewLocal' calls this function with the value of the
    -- @TZ@ environment variable. This function itself is independent of
    -- the value of @TZ@, but if /@identifier@/ is 'P.Nothing' then @\/etc\/localtime@
    -- will be consulted to discover the correct time zone on UNIX and the
    -- registry will be consulted or @/GetTimeZoneInformation()/@ will be used
    -- to get the local time zone on Windows.
    --
    -- If intervals are not available, only time zone rules from @TZ@
    -- environment variable or other means, then they will be computed
    -- from year 1900 to 2037.  If the maximum year for the rules is
