NAME

DateTime::Infinite - Infinite past and future DateTime objects  

SYNOPSIS

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

 

DESCRIPTION

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

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

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.  

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 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.
