Hello, Everyone:

I bought an "atomic clock" in February, 2005, and it has since been
working fine. I live on the eastern coast and now use EDT.

But then at about 2:00 PM, July 20, 2005, I noticed the clock display
"SAT" while it was actually "WED". The Month, Date, Hour, Minute, and
Second were all correct, though. Also, the logo of a radio wave tower
was on, meaning the clock had received the NIST signal for the day.
When I got home after midnight (It was now July 21), the clock
displayed "THU" correctly.

Could it have been that NIST sent a wrong signal for the weekday on
July 20, 2005?


I don't think the WWVB signal has that much information on it. I think only
the minutes and seconds information, because of the different time zones.




No, they can be set right just by getting sync'd up.

The time zone is merely an offset from UTC, which is what WWVB sends out.
You tell the clock what time zone you are in, and it adds the needed
offset to the data recovered from WWVB.
