December 31 1969 or 12/31/1969 will be the date stamp on any e-mail, bulletin board post, article, or other computer data entry item that is not dated. This is because of the way computers keep track of what date it is.
Computers keep track of the date by calculating how many seconds it has been since midnight on the morning of January 1, 1970 (Greenwich mean time). Because January 1. 1970 is the beginning of time for computers, that gives computers their idea that December 31, 1969 is zero time. That is why we receive e-mails with a date of December 31, 1969. http://www.epochconverter.com/
Computer professionals call this phenomenon Unix Epoch, Epoc Time, Unix Time, POSIX Time, Unix Timestamp, or just Epoch.http://www.epochconverter.com/
Because most computers in operation today store and calculate time in a data field of 32 integers, they will run out of room to calculate it on January 19 2038. We might see preparations for Y2038, like we saw for Y2K.http://www.epochconverter.com/
