# ABSTRACT: Infinite past and future DateTime objects
__END__

=head1 NAME
DateTime::Infinite - Infinite past and future DateTime objects
=head1 VERSION
version 1.46
=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 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 returns 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".
This also applies to methods that are compound stringifications, which return
the same strings even for things like C<ymd()> or C<iso8601()>
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.

=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.
Bugs may be submitted at L<https://github.com/houseabsolute/DateTime.pm/issues>.
There is a mailing list available for users of this distribution,
L<mailto:datetime@perl.org>.
I am also usually active on IRC as 'autarch' on C<irc://irc.perl.org>.
