Note that the clock in the Vetenari kit is just a cheap quartz clock 
like you could get anywhere, and the replacement board it comes with 
isn't of any use if you're trying to do something different. Basic 
quartz clocks are not a good choice for hacking into a precision display 
because they can only tick forward in one second increments, with no way 
to know what time is being displayed nor a reasonable way to adjust 
forward or backward an hour for daylight time changes. In other words, 
you can make it tick precisely but you can't really set it.

I'm sort of interested in getting an analog WWVB type clock and seeing 
how much work it would be to coopt *that* hardware since it is designed 
to set arbitrary times, but I have a feeling I'd be better served making 
my own mechanics with a stepper motor and reduction gear. Of course a 
digital clock would be much less complicated, which is what Miguel was 
asking about to begin with, but that's not nearly as much fun.
