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