-- 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.

-- | Creates a t'GI.GLib.Structs.TimeZone.TimeZone' corresponding to /@identifier@/. If /@identifier@/ cannot be
-- parsed or loaded, 'P.Nothing' is returned.
-- 
-- /@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
-- available and it is greater than 2037, then it will followed
-- instead.
-- 
-- See
-- <http://tools.ietf.org/html/rfc3339#section-5.6 RFC3339 §5.6>
-- for a precise definition of valid RFC3339 time offsets
-- (the @time-offset@ expansion) and ISO 8601 for the
-- full list of valid time offsets.  See
-- <http://www.gnu.org/s/libc/manual/html_node/TZ-Variable.html The GNU C Library manual>
-- for an explanation of the possible
