# DateTime::Infinite(3pm)

Infinite past and future DateTime objects

## NAME

DateTime::Infinite - Infinite past and future DateTime objects

## VERSION

version 1.67

## SYNOPSIS

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

## DESCRIPTION

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

The objects are always in the "floating" timezone, and this cannot be changed.

## 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 returns the string representation of positive or negative infinity used by your system. For example, on my system calling `"$dt->year"`\> returns a number which when printed appears either "Inf" or "-Inf".

This also applies to methods that are compound stringifications, which return the same strings even for things like `"$dt->ymd"` or `"$dt->iso8601"`

The object is not mutable, so the `"$dt->set"`, `"$dt->set_time_zone"`, and `"$dt->truncate"` methods are all do-nothing methods that simply return the object they are called with.

Obviously, the `"$dt->is_finite"` method returns false and the `"$dt->is_infinite"` method returns true.

## 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.

Bugs may be submitted at \<https://github.com/houseabsolute/DateTime.pm/issues\>.
