| 86 | =head1 NAME | ||||
| 87 | |||||
| 88 | DateTime::Infinite - Infinite past and future DateTime objects | ||||
| 89 | |||||
| 90 | =head1 SYNOPSIS | ||||
| 91 | |||||
| 92 | my $future = DateTime::Infinite::Future->new; | ||||
| 93 | my $past = DateTime::Infinite::Past->new; | ||||
| 94 | |||||
| 95 | =head1 DESCRIPTION | ||||
| 96 | |||||
| 97 | This module provides two L<DateTime.pm|DateTime> subclasses, | ||||
| 98 | C<DateTime::Infinite::Future> and C<DateTime::Infinite::Past>. | ||||
| 99 | |||||
| 100 | The objects are in the "floating" timezone, and this cannot be | ||||
| 101 | changed. | ||||
| 102 | |||||
| 103 | =head1 BUGS | ||||
| 104 | |||||
| 105 | There seem to be lots of problems when dealing with infinite numbers | ||||
| 106 | on Win32. This may be a problem with this code, Perl, or Win32's IEEE | ||||
| 107 | math implementation. Either way, the module may not be well-behaved | ||||
| 108 | on Win32 operating systems. | ||||
| 109 | |||||
| 110 | =head1 METHODS | ||||
| 111 | |||||
| 112 | The only constructor for these two classes is the C<new()> method, as | ||||
| 113 | shown in the L<SYNOPSIS|/SYNOPSIS>. This method takes no parameters. | ||||
| 114 | |||||
| 115 | All "get" methods in this module simply return infinity, positive or | ||||
| 116 | negative. If the method is expected to return a string, it return the | ||||
| 117 | string representation of positive or negative infinity used by your | ||||
| 118 | system. For example, on my system calling C<year()> returns a number | ||||
| 119 | which when printed appears either "inf" or "-inf". | ||||
| 120 | |||||
| 121 | The object is not mutable, so the C<set()>, C<set_time_zone()>, and | ||||
| 122 | C<truncate()> methods are all do-nothing methods that simply return | ||||
| 123 | the object they are called with. | ||||
| 124 | |||||
| 125 | Obviously, the C<is_finite()> method returns false and the | ||||
| 126 | C<is_infinite()> method returns true. | ||||
