NAME

DateTime::Format::Epoch::TAI64 - Convert DateTimes to/from TAI64 values

SYNOPSIS

use DateTime::Format::Epoch::TAI64;

my $formatter = DateTime::Format::Epoch::TAI64->new();

my $dt2 = $formatter->parse_datetime( ???? );
 # 2003-04-28T00:00:00

$formatter->format_datetime_as_string($dt2);
 # ????

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. Apart from one new method, the only difference is the constructor.

  • new()

    Constructor of the formatter/parser object. It has no parameters.

  • format_datetime_as_string( $dt )

    Returns the TAI64 value as an 8 byte string.

BUGS

Before the introduction of the leap seconds in 1972, the relation between TAI and UTC was irregular. In this module, it is assumed that the difference TAI-UTC was 10 seconds constantly. Any errors introduced by this assumption come from the irregularity of UTC, and are not TAI64's fault or mine.

SUPPORT

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