====Read a TAI64N timestamp in human readable format====
+
[http://cr.yp.to/daemontools/tai64nlocal.html tai64nlocal] converts precise TAI64N timestamps to a human-readable format.
+
tai64nlocal reads lines from stdin. If a line does not begin with @, tai64nlocal writes it to stdout without change. If a line begins with @, tai64nlocal looks for a timestamp after the @, in the format printed by tai64n, and writes the line to stdout with the timestamp converted to local time in ISO format: YYYY-MM-DD HH:MM:SS.SSSSSSSSS.
