[time-nuts] Epoch rollover ?

Bruce,

I'm wondering whether there may be a glitch in the firmware supplied on that
unit. The fact that it worked fine up until the other day, and then reverted
its date seems rather odd. I don't believe it's anything to do with cross
correlation as has been suggested. Unfortunately Odetics is now FEI-Zyfer,
and those units are not supported any more, and the guy who designed them
isn't there anymore either.

Hi, gang,

	Did we just have another GPS epoch rollover? My trusty old Odetics
425 seems to believe the date is March 4th, 1992.

	I could probably correct it in firmware, if I looked hard and long
enough, but the ToD is still correct and the frequency standard is staying
nicely locked. Not sure if recovering the correct Julian date is worth the
effort.

	Thanks much.
