POSIX.1-2008 TC2:
[CX] The strftime_l() function shall be equivalent to the strftime()
   function, except that the locale data used is from the locale
   represented by locale.
[CX] The behavior is undefined if the locale argument to strftime_l()
   is the special locale object LC_GLOBAL_LOCALE or is not a valid locale
   object handle.
