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
Now you are smart.
