As you know, UNIX time is counted in seconds since Thursday, January 1 1970 Midnight (called the Epoch).

For the last three years admins around the world have been watching double-ones in logs’ timestamps, like in

1123456789

Today it’s all different.

The 1200000000th second since the “epoch” was reached on Thu Jan 10 21:20:00 2008.
For a few more hours to come the nice sight of “12000” can be observed in your logs. Have a look.

Note that we are ultimately heading towards the 2147483647th second (2 power 31 less 1), on which the time counters of 32-bit computers will overflow on Tue Jan 19 03:14:07 2038 and the time will start over from Thu Jan 1 1970 00:00:00 GMT (or from Fri Dec 13 20:45:52 1901, depending on whom you ask).
