If you try your probe on EVERY pin of that Chip, there should be some pulsing on at least 1 pin....
If not, the Crystal (or chip?) has died.

edit : the MC14584BCP is just a cmos hex schmidt trigger IC, not a timeclock IC.
I'd say that chip (with crystal) is the main 32khz oscillator feeding elsewhere.

Is your crystal the tiny cylinder shape? about 3mm wide by 10mm long?
I have a bunch of them, if you want me to bring one to the meet this Saturday?
