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?
