.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module can convert a DateTime object (or any object that can be
converted to a DateTime object) to a \s-1TAI64\s0 value. The \s-1TAI64\s0 timescale
covers the entire expected lifespan of the universe (at least, if you
expect the universe to be closed).
.SH "METHODS"
.IX Header "METHODS"
Most of the methods are the same as those in DateTime::Format::Epoch.
The only difference is the constructor.
.IP "\(bu" 4
new( [format => 'string'] )
.Sp
Constructor of the formatter/parser object. If the optional format
parameter is set to 'string', \s-1TAI64\s0 values will be expected to be 8
byte strings.
.SH "SUPPORT"
.IX Header "SUPPORT"
