So pretty much, if one is using the tones from a RELIABLE radio
station, they can count on setting their watch approximately 5-10
seconds ahead(of that station) and probably be very close to WWVB or
WWVH.


Why not make that 'reliable' station WWV to start with?

I should have clarified my statement "if {{an average Joe/Jane}} is
using the tones from {{1010 wins}}," Then synch timepiece to slightly
ahead of the tone from the station.

I should be noted that those of us who are SWL's or AMBCB DX'ers (a form
of
nerd) are much more concerned with the "exact" time, whereas the vast
majority of people on Earth find +/- 5 minutes to be quite adequate. Some
even far less than that (folks here figure if they show up to work less
than
half an hour late, they're still considered to be "on time")

The clock we punch in at work gains 1 minute per month! And it
replaced one - of the same make & model - that used to gain TWO
minutes per month. The same exact make & model, in another department
staffed by the same contractor that I work for, LOSES a minute per
month. LOL!

Wait a minute Brenda - HERE IT IS!! I drop my card into this pile of
gears every freakin day:

I can't believe I found the sunovabitch on line!! This clock sucks.
No two keep the same time - or the right time, for that matter.



You know what? It's strange, in a way, but my personal experience is that
when clocks went from analog to digital, they stopped keeping good time. The
old synchronous motors had more than enough flywheel effect that if the line
frequency DID happen to shift for a moment or two, the clock didn't change
speed with it. Now that everything is running off of a crystal (32.* KHz?)
that is mass produced by the billions and no two are alike, nothing keeps
decent time anymore. Were there ever AC operated digital clocks that simply
got their sync from the line?
