NAME

DateTime::Infinite - Infinite past and future DateTime objects

VERSION

version 1.59

SYNOPSIS

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

DESCRIPTION

This module provides two DateTime subclasses, DateTime::Infinite::Future and DateTime::Infinite::Past.

The objects are always in the "floating" timezone, and this cannot be changed.

METHODS

The only constructor for these two classes is the new method, as shown in the "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 $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 $dt->ymd or $dt->iso8601

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

Obviously, the $dt->is_finite method returns false and the $dt->is_infinite method returns true.

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 https://github.com/houseabsolute/DateTime.pm/issues.

There is a mailing list available for users of this distribution, mailto:datetime@perl.org.
