Hi Everyone, This is something that I've wondered about for a while, though it doesn't really have anything to do with my daily life. If I want to get two clocks or watches in dead sync, how do I do it? I'm thinking of the scene in Back To The Future when Doc Brown has the two digital watches and they're running in dead sync. Do you need special watches to do that? Is there a difference between digital and analogue? Is there a special technique when it comes to wall clocks (if I wanted to have three clocks for three seperate time zones, but have the second hands sweeping in sync, would this be possible?) I seem to remember something about clocks in public schools being controlled by one "master" clock, but that isn't really practical for the average user. I know that quartz digital watches aren't 100% accurate either, so there would be drift over a length of time... Any comments on this would be appreciated!
