=head1 NAME
Test::Time - Overrides the time() and sleep() core functions for testing
=head1 SYNOPSIS
use Test::Time;
# Freeze time
my $now = time();
# Increment internal time (returns immediately)
sleep 1;
# Return internal time incremented by 1
my $then = time();
=head1 DESCRIPTION
Test::Time can be used to test modules that deal with time. Once you C<use> this
module, all references to C<time>, C<localtime> and C<sleep> will be internalized.
You can set custom time by passing time => number after the C<use> statement:
use Test::Time time => 1;
my $now = time; # $now is equal to 1
sleep 300; # returns immediately, displaying a note
my $then = time; # $then equals to 301
