Please remove me from the mailing list. Too much email concerning this issue. I would suggest meeting in a common virtual space and having a live discussion, rather then "replying all" when continuing to have this conversation.

If you care *that* much, you need something fancier, e.g. an atomic
clock. :-) I seem to remember some news article in the past year or so indicating that there might be some new type of atomic clock coming out that would be less expensive, but I can't seem to find it with some simple Googling.
There was a new clock that's particularly compact (an inch or so max
dimension). It wasn't clear just how it works, but it sounded like it's comparable in stability to a rubidium clock.
In the meantime, I think the cheapest atomic time source is a GPS box.
Probably related to this:
Now an atomic clock-on-a-chip is available that is the result of 10 years of government-funded research and development. The chip is not cheap — $1,500 — but it costs less than conventional atomic clocks and the price is sure to go down as manufacturing gears up to meet demand from military applications.
