Epoch time and Epoch time milestone

The Unix epoch (also known as Unix Time Stamp) is the representation of time as the number of non-leap seconds since 00:00:00 UTC on January 1, 1970. It is introduced by Unix operating system, , standardised in POSIX. The clock is used not just by Unix, but also by Linux, Java, JavaScript, Mac OS X, and various other technologies. In the fields of chronology and periodization, an epoch means an instant in time chosen as the origin of a particular era. The "epoch" then serves as a reference point from which time is measured. Time measurement units are counted from the epoch so that the date and time of events can be specified unambiguously.

On Friday, February 13th 2009, 23:31:30 UTC, it will be exactly 1,234,567,890 seconds since the beginning of Epoch Time, which was on midnight of January 1, 1970. So it's the time for Unix nerds to celebrate 1234567890 :-)

And here's a site that's counting down to that momentous event: http://coolepochcountdown.com/
