[time-nuts] Lady Heather and LeapSecond
It should wind up in the standard Lady Heather directory... depends upon the operating system and how the program was started. From the keyboard in Lady Heather, type ? That will bring up the command line option help. Scroll/page down to the end of the info and there will be a line that says something like "Put heather.cfg in directory...

The problems with the Z3801 (and Z3812 / KS23xxx) devices is they expect the leapsecond to occur at the end of March/June/Sept/Dec. So if the leapsecond is announced more than 3 months in advance they calculate the wrong day of the leapsecond. I suspect that they would mess up any leapsecond not at the end of March/June/Sept/Dec. I don't know if the HP53xxx devices have the same firmware bug... After a couple of days after 30 Sep the Z3801A and Z3812A did not show a leap second was pending, so I power-cycled the Z3801A and it started showing the leap pending again. I left the Z3812A running and after 3 days it started showing the proper leap second pending. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

> it did when my Z3801A did a false leap-second at the end of September. Was there a similar problem/opportunity at the end of Oct? Should we watch at the end of Nov (last chance for a while)? What did the Z3801A do? Was the bug in the Z3801A or in an ancient version of ntpd without the fix I added (ages ago) to handle the leap second getting announced more than a month early? -- These are my opinions.
