-- libtai is a library for storing and manipulating dates and times. libtai supports two time scales: (1) TAI64, covering a few hundred billion years with 1-second precision; (2) TAI64NA, covering the same period with 1-attosecond precision. Both scales are defined in terms of TAI, the current international real time standard. Submitted by Brian J. Kifiak <bk@rt.fm> checked by wilfried@ (thanks!)
