NAME
       [Time::gmtime](https://www.chedong.com/phpMan.php/perldoc/Time%3A%3Agmtime/markdown) - by-name interface to Perl's built-in gmtime() function

SYNOPSIS
        use [Time::gmtime](https://www.chedong.com/phpMan.php/perldoc/Time%3A%3Agmtime/markdown);
        $gm = gmtime();
        printf "The day in Greenwich is %s\n",
           (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $gm->wday() ];

        use [Time::gmtime](https://www.chedong.com/phpMan.php/perldoc/Time%3A%3Agmtime/markdown) qw(:FIELDS);
        gmtime();
        printf "The day in Greenwich is %s\n",
           (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $tm_wday ];

        $now = gmctime();

        use [Time::gmtime](https://www.chedong.com/phpMan.php/perldoc/Time%3A%3Agmtime/markdown);
        use [File::stat](https://www.chedong.com/phpMan.php/perldoc/File%3A%3Astat/markdown);
        $date_string = gmctime(stat($file)->mtime);

DESCRIPTION
       This module's default exports override the core gmtime() function,
       replacing it with a version that returns "[Time::tm](https://www.chedong.com/phpMan.php/perldoc/Time%3A%3Atm/markdown)" objects.  This
       object has methods that return the similarly named structure field name
       from the C's tm structure 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](https://www.chedong.com/phpMan.php/perldoc/CORE%3A%3Agmtime/markdown)() function.

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

NOTE
       While this class is currently implemented using the [Class::Struct](https://www.chedong.com/phpMan.php/perldoc/Class%3A%3AStruct/markdown)
       module to build a struct-like class, you shouldn't rely upon this.
