Another thing to watch out for on these 'atomic clocks' appears to be
nearby lightning strikes. I have 3 of the clocks here. Two are not
affected but the other one, after any fairly nearby thunderstorm,
requires that I remove the battery, let it completely discharge all
energy held within (this takes a few minutes as they are very low
power drain and apparently have decent sized caps inside) and restart it.
It will then lock up and stay that way until the next thunderstorm
rolls through.
But once a storm rolls through, it will unlock and refuse to re-lock
not matter how many times I press the 'resync' button. Something
appears to get hosed up in its OS and it declines every attempt to
resync it.
I can tell when it has lost sync by checking the little 'sync' icon.
And, of course, the time is off . . .

Unfortunately the consumer clocks seem to attempt to sync between
0200 and 0400 *local* (display) time regardless of the time zone.
I have a couple that would display UTC but when I set them to do
so they never sync because their "window" does not seem to include
the optimum propagation window.

I reset my shack clock to local time, CST, yesterday evening and this
morning it is correct to the second (it was running about 45 seconds
fast). Now I'll have to see if it stays in sync over the long term.
