I have four atomic regulated clocks in my home, and another tiny atomic
clock on the bedside table. One of them doesn't get the signal at all
for some reason so I have to manually set it, and two of them usually
don't get the signal until the next evening.

Atomic, hahahahaha

These clocks receive the radio signal from NIST in Colorado to
synchronize. The signal is sent as GMT. The offset from Greenwich is set
manually, and the user chooses whether to display DST. That the time
change takes place at 2 am is hard wired. A bit of code (I think it's
literally two bits) is sent on time change day so that no reprogramming
is required when the law is amended. If the device misses receiving the
code, it won't change over at 2 am and the changeover happens when it
next synchronizes.

Then I have this little Sony alarm clock in the living room on my computer
hutch that isn't atomic but it always recognizes the time change.

Then the provisions of the 2005 amendment is hard wired in. I have VCRs
with the pre-2005 provisions hard wired in, which forced me to make the
change manually. They aren't hooked up at the moment.

That still leaves the
GE kitchen under-cabinet clock, an old Coca-Cola clock, and my watch
that I have to manually set.

I never bother with resetting the clock in the car, I just keep it on
DST all year.

My vehicle has a network clock from GPS but I have to manually change
the time offset, plus an analog clock that is not networked.
