NAME

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

SYNOPSIS

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

DESCRIPTION

This module's default exports override the core gmtime() function, replacing it with a version that returns ``Time::tm'' 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() 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 module to build a struct-like class, you shouldn't rely upon this.
