MirOS Manual: Time::gmtime(3p)

     Time::gmtime - by-name interface to Perl's built-in gmtime()


      use Time::gmtime;
      $gm = gmtime();
      printf "The day in Greenwich is %s\n",
         (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ gm->wday() ];

      use Time::gmtime w(:FIELDS;
      printf "The day in Greenwich is %s\n",
         (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ gm_wday() ];

      $now = gmctime();

      use Time::gmtime;
      use File::stat;
      $date_string = gmctime(stat($file)->mtime);


     This module's default exports override the core gmtime()
     function, replacing it with a version that returns
     "Time::tm" objects. This object has methods that return the
     similarly named structure field name from the C's tm struc-
     ture from time.h; namely sec, min, hour, mday, mon, year,
     wday, yday, and isdst.

     You may also import all the structure fields directly into
     your namespace as regular variables using the :FIELDS import
     tag.  (Note that this still overrides your core functions.)
     Access these fields as variables named with a preceding
     "tm_" in front their method names.  Thus, "$tm_obj->mday()"
     corresponds to $tm_mday if you import the fields.

     The gmctime() function provides a way of getting at the
     scalar sense of the original CORE::gmtime() function.

     To access this functionality without the core overrides,
     pass the "use" an empty import list, and then access func-
     tion functions with their full qualified names. On the other
     hand, the built-ins are still available via the "CORE::"


     While this class is currently implemented using the
     Class::Struct module to build a struct-like class, you
     shouldn't rely upon this.
