-- | Creates a newly allocated string representing the requested /@format@/.
-- 
-- The format strings understood by this function are a subset of the
-- @/strftime()/@ format language as specified by C99.  The %D, %U and %W
-- conversions are not supported, nor is the \'E\' modifier.  The GNU
-- extensions %k, %l, %s and %P are supported, however, as are the
-- \'0\', \'_\' and \'-\' modifiers.
-- 
-- In contrast to @/strftime()/@, this function always produces a UTF-8
-- string, regardless of the current locale.  Note that the rendering of
-- many formats is locale-dependent and may not match the @/strftime()/@
-- output exactly.
-- 
-- The following format specifiers are supported:
-- 
-- * %a: the abbreviated weekday name according to the current locale
-- * %A: the full weekday name according to the current locale
-- * %b: the abbreviated month name according to the current locale
-- * %B: the full month name according to the current locale
-- * %c: the preferred date and time representation for the current locale
-- * %C: the century number (year\/100) as a 2-digit integer (00-99)
-- * %d: the day of the month as a decimal number (range 01 to 31)
-- * %e: the day of the month as a decimal number (range  1 to 31)
-- * %F: equivalent to @%Y-%m-%d@ (the ISO 8601 date format)
-- * %g: the last two digits of the ISO 8601 week-based year as a
-- decimal number (00-99). This works well with %V and %u.
-- * %G: the ISO 8601 week-based year as a decimal number. This works
-- well with %V and %u.
-- * %h: equivalent to %b
-- * %H: the hour as a decimal number using a 24-hour clock (range 00 to 23)
-- * %I: the hour as a decimal number using a 12-hour clock (range 01 to 12)
-- * %j: the day of the year as a decimal number (range 001 to 366)
-- * %k: the hour (24-hour clock) as a decimal number (range 0 to 23);
-- single digits are preceded by a blank
-- * %l: the hour (12-hour clock) as a decimal number (range 1 to 12);
-- single digits are preceded by a blank
-- * %m: the month as a decimal number (range 01 to 12)
-- * %M: the minute as a decimal number (range 00 to 59)
-- * %p: either \"AM\" or \"PM\" according to the given time value, or the
-- corresponding  strings for the current locale.  Noon is treated as
-- \"PM\" and midnight as \"AM\".
-- * %P: like %p but lowercase: \"am\" or \"pm\" or a corresponding string for
-- the current locale
-- * %r: the time in a.m. or p.m. notation
-- * %R: the time in 24-hour notation (%H:%M)
-- * %s: the number of seconds since the Epoch, that is, since 1970-01-01
-- 00:00:00 UTC
-- * %S: the second as a decimal number (range 00 to 60)
-- * %t: a tab character
-- * %T: the time in 24-hour notation with seconds (%H:%M:%S)
-- * %u: the ISO 8601 standard day of the week as a decimal, range 1 to 7,
--  Monday being 1. This works well with %G and %V.
-- * %V: the ISO 8601 standard week number of the current year as a decimal
-- number, range 01 to 53, where week 1 is the first week that has at
-- least 4 days in the new year. See 'GI.GLib.Structs.DateTime.dateTimeGetWeekOfYear'.
-- This works well with %G and %u.
-- * %w: the day of the week as a decimal, range 0 to 6, Sunday being 0.
-- This is not the ISO 8601 standard format -- use %u instead.
-- * %x: the preferred date representation for the current locale without
-- the time
-- * %X: the preferred time representation for the current locale without
-- the date
-- * %y: the year as a decimal number without the century
-- * %Y: the year as a decimal number including the century
-- * %z: the time zone as an offset from UTC (+hhmm)
-- * %:z: the time zone as an offset from UTC (+hh:mm).
-- This is a gnulib @/strftime()/@ extension. Since: 2.38
-- * %[z](#signal:z): the time zone as an offset from UTC (+hh:mm:ss). This is a
-- gnulib @/strftime()/@ extension. Since: 2.38
-- * %:[z](#signal:z): the time zone as an offset from UTC, with : to necessary
-- precision (e.g., -04, +05:30). This is a gnulib @/strftime()/@ extension. Since: 2.38
-- * %Z: the time zone or name or abbreviation
-- * %%: a literal % character
-- 
-- 
-- Some conversion specifications can be modified by preceding the
-- conversion specifier by one or more modifier characters. The
-- following modifiers are supported for many of the numeric
-- conversions:
-- 
-- * O: Use alternative numeric symbols, if the current locale supports those.
-- * _: Pad a numeric result with spaces. This overrides the default padding
-- for the specifier.
-- * -: Do not pad a numeric result. This overrides the default padding
-- for the specifier.
-- * 0: Pad a numeric result with zeros. This overrides the default padding
-- for the specifier.
-- 
-- 
-- Additionally, when O is used with B, b, or h, it produces the alternative
-- form of a month name. The alternative form should be used when the month
-- name is used without a day number (e.g., standalone). It is required in
-- some languages (Baltic, Slavic, Greek, and more) due to their grammatical
-- rules. For other languages there is no difference. %OB is a GNU and BSD
-- @/strftime()/@ extension expected to be added to the future POSIX specification,
-- %Ob and %Oh are GNU @/strftime()/@ extensions. Since: 2.56
