NAME¶
DateTime::Infinite - Infinite past and future DateTime objects
VERSION¶
version 1.12
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.
