#Clock accuracy
Bill,
Just for reference…
About 4 months ago, I set the clock in Insider to the NBS time signal
(it's a local phone call for me) and then checked it a week later…it was
still right on. Since I saw your message tonight about the chip accuracy of
several of the clock devices, I thought I'd go check to see how Insider is
holding up. It's now 3 seconds slow from NBS…that's not bad! 3 seconds in 4
months (or so) means that over the life of the clock chip on Insider (10 years)
it might be a whole 2 minutes off by the time the battery dies!
My A-time on the other hand, on odd occasions (I could never get a
pattern) would suddenly lose a whole month! The clock accuracy (Time of Day)
would drift about 2 seconds per month. I will say that I have one of the
earlier A-Time's and mine does have a trimmer cap (and the replaceable battery)
if I were so inclined to adjust it. I understand Akron used 2 different chips,
unfortunately…I have no idea which chip is in mine since both chips have no
part numbers on them. If it matters, the board in my A-Time says v2.0.
