Not exactly sure how a coworker managed to have this happen but he has done it twice now, however it’s not frequent (a few months apart). Anyway on to the issue: The published date on the front-end displays as something like Dec. 5, 1969, even though the entry was just published. I go into the cp to check it out and the Date column on the entries listing page reads ‘0’. When I go into the entry the date is set correctly (e.g. 2012-06-05 08:54 AM) and a simple Save Revision fixes the date everywhere. I’m curious if there have been similar issues reported, and what might be going on.

P.S.
http://en.wikipedia.org/wiki/Unix_time
The Unix epoch is the time 00:00:00 UTC on 1 January 1970 (or 1970-01-01T00:00:00Z ISO 8601)
so usually if the time is 0 or null you will see Dec 31, 1969
