However, on re-reading the original poster's request, I see he was look for "time synchronization" hardware or software. To qualify, I think such hardware ought to provide for performing the synchronization function -- such as, for instance, outputting a one-pulse-per-second signal at its estimate of the exact UTC (or TAI) second boundary. Otherwise, the equipment would be a clock, but not "time synchronization hardware." -- James Maynard Salem, Oregon, USA _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
