Corey: So far, there have been many previous messages about the 60Hz
timebase of the AC line "being fixed-in-phase" with the rest of the nation.
I come from Illinois, and our state has the highest percentage of nuclear
power use in the U.S. brought to us by Commonwealth Edison (so far so good
:) ). Anyways, I used to hear the worst things from my high school
electronics teacher about Florida's infamous 'brown-outs.' I do believe a
lot of timing electronics does make use of the AC line (Most VCR's do), and
I'm surprised because Japan (biggest manufacturer) has both 50/60Hz @
100V rms. Their modern clocks now do not have a 50/60Hz switch.

One case in point is that the battery back-up mentioned will NOT be viable
with the 60Hz method.

Lastly, I'd like to apologize to everyone for the unintended 'echos' of my
original message. I'm sorry that happened, I do not know why it did, I only
see it once on our site (although messed up), and I have revieved a lot of
concerned e-mail about it.
