A subscriber to Outages who wishes to remain nameless passes along the
pointer to this story: Apparently, either tick or tock got rebooted 
yesterday, and came up with its local clock set to 2000.  And lots of
people believed it.

Did you believe it?  Why?

(Yes, those are just rhetorical questions, intended to make people examine
their NTP architecture more closely.  :-)
