       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).

       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.
