If a date is showing as “December 31, 1969”, it has nothing to do with the server’s time being REALLY off or anything like that.
WordPress and most other web software store date/times in a Unix timestamp, or simply put, the number of seconds since January 1st, 1970 00:00, the Unix epoch. December 31st, 1969 is happening because WordPress or whatnot is subtracting a few hours to adjust for GMT offset.
characterdriven: first off, please create your own thread next time instead of hijacking another thread. ?? Your “issue” is not an issue at all. It’s “intended”. Drafts do not get a post time until they are actually posted. Until they are, they have a post time of “0”. Do not worry about it. ??
HollyM: are you still around and looking for a solution? If so, more details are needed. Where are you seeing this date? In drafts? Or what?
