Matey,
Joe your idea is terrific and simple. I've seen photos of transit telescopes (not Transit in the sense of surveying) that are at Greenwich and have found the idea fascinating.
Oh...another thing- US power companies use 60 Hz for in power transmission and that frequency is used by electric (plugged into the wall) clocks which are as accurate as that frequency- very accurate.
No doubt the PICKY PICKY devices of life aren't satisfied with anything but 1 billionth of a second accuracy.
I'm no expert in these matters but I've often wondered why accuracy in timing of computer devices is so critical?
The USNO does provide THE MASTER CLOCK and if THEY (the USNO) doesn't keep time then we're in big trouble...and probably will end up like the first few minutes of 2001 A Space Odyssey. But it really shouldn't be difficult to send out time signals however the means.
