The internet and programming languages use unix time, which is just a number that is simply the number of seconds that has elapsed since 12/31/1969 at midnight (or 1/1/1970 at 0:00am, which is the same thing). So a date of 0 is usually interpretted as 12/31/1969.I am getting weird things with my e-mail this morning... just got three e-mails.
One looks normal and two have a date of 12/31/1969???
... not that this explains anything, I'm just posting in case you didn't know that little tidbit.
