This Friday the 13th at 3:31:30pm PST, it's time to party like it's 1234567890 - 'cause it is! (UNIX time)
Basically, most computer count time as the number of seconds since January 1, 1970 UTC. If u r geeky enough, throw a party! See 1234567890day.com for more. (Since I'm in Pittsburgh, I'll be partying at 6:31pm EST.)
