=head1 NAME
Time::localtime - by-name interface to Perl's built-in localtime() function
=head1 SYNOPSIS
use Time::localtime;
printf "Year is %d\n", localtime->year() + 1900;
$now = ctime();
use Time::localtime;
use File::stat;
$date_string = ctime(stat($file)->mtime);
=head1 DESCRIPTION
This module's default exports override the core localtime() 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 F<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 C<tm_> in front their method names.
Thus, C<$tm_obj-E<gt>mday()> corresponds to $tm_mday if you import
the fields.
The ctime() function provides a way of getting at the
scalar sense of the original CORE::localtime() function.
To access this functionality without the core overrides,
pass the C<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 C<CORE::> pseudo-package.
=head1 NOTE
While this class is currently implemented using the Class::Struct
module to build a struct-like class, you shouldn't rely upon this.
