Dave, I think we've been through this before. The NIST radio timecode can handle either insertion or deletion of leap seconds. The LS bit tells you if a leap second is pending; the sign of DUT1 bit(s) tell you if the leap is positive (inserted) or negative (deleted). So there is provision; there is no problem. /tvb http://www.leapsecond.com/notes/leap-watch.htm _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
