Time::gmtime - by-name interface to Perl's built-in gmtime() function
- 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 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.
While this class is currently implemented using the Class::Struct module to build a struct-like class, you shouldn't rely upon this.
