   5 NAME
   6        strftime, strftime_l cftime, ascftime - convert date and time to string

  10 
  11        size_t strftime(char *restrict s, size_t maxsize,
  12             const char *restrict format,
  13             const struct tm *restrict timeptr);
  14 
  15        size_t strftime_l(char *restrict s, size_t maxsize,
  16             const char *restrict format,
  17             const struct tm *restrict timeptr, locale_t loc);
  18 
  19        int cftime(char *s, char *format, const time_t *clock);
  20 
  21        int ascftime(char *s, const char *format,
  22             const struct tm *timeptr);

  25 DESCRIPTION
  26        The strftime(), strftime_l(), ascftime(), and cftime() functions place

 416 
 417        The conversion specifications for %g, %G, %Eg, %EG, and %Og were added
 418        in the Solaris 7 release.  This change was based on the public review
 419        draft of the ISO C9x standard at that time. The %g and %G
 420        specifications were adopted in the formal standard.  The other two were
 421        not, and should not be used in portable applications.
 422 
 423        The conversion specification for %u was changed in the Solaris 8
 424        release.  This change was based on the XPG4 specification.
 425 
 426        If using the %Z specifier and zoneinfo timezones and if the input date
 427        is outside the range 20:45:52 UTC, December  13, 1901 to 03:14:07 UTC,
 428        January 19, 2038, the timezone name may not be correct.
 429 
 430        The conversion specification for %+ was added in illumos.  It is not
 431        part of any standard, although it is available on a number of other
 432        platforms.  Its use is discouraged for conforming applications.
