DateTime::Infinite - Infinite past and future DateTime objects


DateTime::Infinite - Infinite past and future DateTime objects


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


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

The objects are in the ``floating'' timezone, and this cannot be changed.


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.


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 return the string representation of positive or negative infinity used by your system. For example, on my system calling year() returns a number which when printed appears either ``inf'' or ``-inf''.

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

Obviously, the is_finite() method returns false and the is_infinite() method returns true.
