# ABSTRACT: Infinite past and future DateTime objects
=pod
=head1 NAME
DateTime::Infinite - Infinite past and future DateTime objects
=head1 VERSION
version 0.70
=head1 SYNOPSIS
my $future = DateTime::Infinite::Future->new();
my $past = DateTime::Infinite::Past->new();
=head1 DESCRIPTION
This module provides two L<DateTime.pm|DateTime> subclasses,
C<DateTime::Infinite::Future> and C<DateTime::Infinite::Past>.
The objects are in the "floating" timezone, and this cannot be
changed.
=head1 BUGS
There seem to be lots of problems when dealing with infinite numbers
on Win32. This may be a problem with this code, Perl, or Win32's IEEE
math implementation. Either way, the module may not be well-behaved
on Win32 operating systems.
=head1 METHODS
The only constructor for these two classes is the C<new()> method, as
shown in the L<SYNOPSIS|/SYNOPSIS>. This method takes no parameters.
All "get" methods in this module simply return infinity, positive or
negative. If the method is expected to return a string, it return the
string representation of positive or negative infinity used by your
system. For example, on my system calling C<year()> returns a number
which when printed appears either "inf" or "-inf".
The object is not mutable, so the C<set()>, C<set_time_zone()>, and
C<truncate()> methods are all do-nothing methods that simply return
the object they are called with.
Obviously, the C<is_finite()> method returns false and the
C<is_infinite()> method returns true.
