On Feb, Friday 13, 2009 Unix time Will Be 1234567890

Unix time, or POSIX time, is a system for describing points in time, defined as the number of seconds elapsed since midnight Coordinated Universal Time (UTC) of January 1, 1970, not counting leap seconds. It is widely used not only on Unix-like operating systems but also in many other computing systems. It is neither a linear representation of time nor a true representation of UTC (though it is frequently mistaken for both) as the times it represents are UTC but it has no way of representing UTC leap seconds (e.g. 1998-12-31 23:59:60).

At 11:31:30pm UTC on Feb 13, 2009, Unix time will reach 1,234,567,890. You can verify this as follows:

$ date -d@1234567890

Sample output:

Fri Feb 13 17:31:30 CST 2009
