[time-nuts] Three Phase Power

What will be funny is when all the neighbourhood hoodlums start stealing
all the antenna modules off the poles, or an enterprising teen electronics
whiz kid starts jamming the signal. I can see antenna modules piling up at
scrap yards, sitting beside the aluminum pop cans, as I speak.

My major worry is about the time base they use, and whether we will end up
getting the dirty end of the stick, so to speak. They figure Joe Blow down
on the corner don't know enough about this stuff to question it, but just a
few of us do. Also, as John mentioned, we have ignorant politicians who
will go along with it. Also, like you, I haven't seen much printed about
them, just what I've found. I figure, if we're footing the bill, I want it
as precise as possible, and not in just the amount I use, but over the
amount of time I used it.

I'll leave a parting shot at AEP on this. When I closed up the building I
had the shop in, I went down to our AEP office at the time, and paid off my
bill, the day after I had them to put a boot on the meter, and a new seal
on it. It was read that day. Well, the next month, I get another bill, and
I take it to AEP, and ask what's up, and show them a time stamped photo of
the meter, with the seal and boot still on it. They had the audacity to
tell me, that it still must have been something using the power, and the
meter had been read, but it had never been tampered with. Now, you tell me
what happened? I never paid that bill either. My guess, it all revolved
around the meter reader.
