UNIX Celebrates Birth Milestone

UNIX is 1 billion (1,000,000,000) seconds old!

Time in UNIX is measured by the number of seconds since the epoch. Epoch is 0000:01, January 1, 1970.

On Saturday, September, 8, 2001, at 8:46:40 PM UNIX was 1 billion seconds old.

How did we figure this out? The following command will return the exact time of the 1 billion second mark (the time on your system must be accurate):

perl -e 'print scalar localtime( 1000000000 )'

Or you can substute 2000000000 in place of 1000000000 to determine when UNIX will be 2 billion seconds old.

So, how old is UNIX? UNIX will be 32 years old on January 1, 2002. Can you tell me how many seconds that will be?

Now you are smart.
