12 my $future = DateTime::Infinite::Future->new();
13 my $past = DateTime::Infinite::Past->new();
14
16 This module provides two DateTime.pm subclasses,
17 "DateTime::Infinite::Future" and "DateTime::Infinite::Past".
18
19 The objects are in the "floating" timezone, and this cannot be changed.
20
22 There seem to be lots of problems when dealing with infinite numbers on
23 Win32. This may be a problem with this code, Perl, or Win32's IEEE math
24 implementation. Either way, the module may not be well-behaved on Win32
25 operating systems.
26
28 The only constructor for these two classes is the "new()" method, as
29 shown in the SYNOPSIS. This method takes no parameters.
30
31 All "get" methods in this module simply return infinity, positive or
32 negative. If the method is expected to return a string, it return the
33 string representation of positive or negative infinity used by your
34 system. For example, on my system calling "year()" returns a number
35 which when printed appears either "inf" or "-inf".
36
37 The object is not mutable, so the "set()", "set_time_zone()", and
38 "truncate()" methods are all do-nothing methods that simply return the
39 object they are called with.
40
41 Obviously, the "is_finite()" method returns false and the
42 "is_infinite()" method returns true.
