Time::gmtime(3) Perl Programmers Reference Guide Time::gmtime(3)NAMETime::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 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);
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:\fIs0: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::" 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.
