In most computer systems, Unix time is a way of describing points in time based on the number of seconds that elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970. On September 9, 2001, Unix time passed 1,000,000,000 seconds. Today, Friday, February 13, at exactly 23:31:30 (UST), Unix time will equal '1234567890'. Some people are planning to party like it's 1234567890.
