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.
