# ABSTRACT: Infinite past and future DateTime objects

__END__

=head1 NAME

DateTime::Infinite - Infinite past and future DateTime objects

=head1 VERSION

version 1.65

=head1 SYNOPSIS

my $future = DateTime::Infinite::Future->new;
  my $past   = DateTime::Infinite::Past->new;

=head1 DESCRIPTION

This module provides two L<DateTime> subclasses, C<DateTime::Infinite::Future>
and C<DateTime::Infinite::Past>.

The objects are always 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>. 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<< $dt->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<< $dt->ymd >> or C<< $dt->iso8601 >>

The object is not mutable, so the C<< $dt->set >>, C<< $dt->set_time_zone >>,
and C<< $dt->truncate >> methods are all do-nothing methods that simply return
the object they are called with.

Obviously, the C<< $dt->is_finite >> method returns false and the C<<
$dt->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>.
