David,

Yes - Once the 'common' Home Clock that is Powered by the
AC Mains is Manually Set : They are Accurate-to-the-Minute :
Day-in and Day-out [.]

And . . . IMHO for Day-to-Day Living - Accurate-to-the-Minute
Is Good Enough !

More Every Day Accurate-to-the-Minute Clocks in our Lives :

* Home Computer Clocks - Self-Setting

* Telephone and Celphone Clocks - Self-Setting

* Cable TV "Set-Top-Box" Clocks - Self-Setting

* The Clock you "See" on the TV - Self-Setting

* The Top-of-the-Hour (TOH) "'Tone" you Hear on the Radio
be it AM -or- FM -or- even a Shortwave Radio Broadcast.

CLOCKS - We Take them for Granted -but- They Are There
Day-after-Day : Accurate-to-the-Minute


i am sure there are a few more to add to the list ~ RHF

I don't know of any clocks that synchronize automatically to WWV or CHU.

There are lots of clocks and watches that synch to the local time
standard. In the USA it would be the 60khz signal from the NIST. I
believe it is WWVB that sends the signal and not WWV but the
difference is not relevant.


* As far as I know there's WWVB and a station in Germany.

The cheapest most accurate clocks are the ones that use the AC mains for
a timebase.

Actually the clocks with the most accurate display would be those that
synchronize daily with a time standard. That would include Atomic
(radio) Clocks and PC Clocks.

Oh yeah. Missed the obvious here. You should be able to find software
utilities that connect to web sites with atomic clocks. That would be
best. There might even be some free utilities that query time servers.

They are accurate to the second,on average. They might speed up for a
while, but then they slow down to compensate (and vice versa).

The Drake R8B clock synchronizes to the power lines, as do many alarm
clocks.

Not relevant? How so? The FCC would fine them if they misidentified so
there is at least some relevance on some level.

Find me a PC for under $10. Same for an atomic watch. And there are
many PCs that wander 10 seconds or more between NTP updates. The
traditional synchronous clock is the champion for staying on the correct
time the best over an extended period of time, without a reset of some kind.

Try to pay attention sparky. The thread is about quartz clocks being sucky.
