I recently turned a HP frequency counter into a style-fitting
clock for our workshop in Danish Computer History Association:
http://ing.dk/artikel/119043-ur-til-tiden
(Google translate does a decent job)
I used a PIC18mumble and a DS3231 RTC.
Since the RTC also tracks day-month-year, it was trivial to let it
run in UTC and program the pic18 to figure out timezone + DST.
Even if you use a uP to count time, it would make good sense to
include a RTC so you don't have to reset the clock after each
power-glitch.

Never attribute to malice what can adequately be explained by incompetence.
