Time::gmtime \- by\-name interface to Perl's built\-in gmtime() function
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 4
\& use Time::gmtime;
\& $gm = gmtime();
\& printf "The day in Greenwich is %s\en",
\& (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $gm\->wday() ];
\&
\& use Time::gmtime qw(:FIELDS);

.SH DESCRIPTION
.IX Header "DESCRIPTION"
This module's default exports override the core \fBgmtime()\fR 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 \fItime.h\fR; namely sec, min, hour,
mday, mon, year, wday, yday, and isdst.
.PP
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 \f(CW\*(C`tm_\*(C'\fR in front their method names. Thus,
\&\f(CW\*(C`$tm_obj\->mday()\*(C'\fR corresponds to \f(CW$tm_mday\fR if you import the fields.
.PP
The \fBgmctime()\fR function provides a way of getting at the
scalar sense of the original \fBCORE::gmtime()\fR function.
.PP
To access this functionality without the core overrides,
pass the \f(CW\*(C`use\*(C'\fR 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 \f(CW\*(C`CORE::\*(C'\fR pseudo-package.
.SH NOTE
.IX Header "NOTE"
While this class is currently implemented using the Class::Struct
module to build a struct-like class, you shouldn't rely upon this.
