  use DateTime::Format::Epoch::TAI64;
  my $dt = DateTime::Format::Epoch::TAI64
                ->parse_datetime( '4611686019483526367' );
   # 2003-06-20T19:49:59

                                                format => 'string' );
  $dt = $str_frmt->parse_datetime( "\x40\0\0\0\x3e\xf3\x69\x6a" );
   # 2003-06-20T19:49:59

## DESCRIPTION

This module can convert a DateTime object (or any object that can be converted to a DateTime object) to a TAI64 value. The TAI64 timescale covers the entire expected lifespan of the universe (at least, if you expect the universe to be closed).

## METHODS

Most of the methods are the same as those in DateTime::Format::Epoch. The only difference is the constructor.

- •

  new( \[format =\> 'string'\] )

  Constructor of the formatter/parser object. If the optional format parameter is set to 'string', TAI64 values will be expected to be 8 byte strings.

## SUPPORT

Support for this module is provided via the datetime@perl.org email list. See http://lists.perl.org/ for more details.
