Hi,
I know in C you use the time() function to get the number of seconds since the epoch, but I can't find a command that does the same thing. There must be a standard UNIX command that does it somewhere right?

Nevermind, I found it:
Code: 
date +%s

If you are using ksh93 you can also use printf "%(%s)T" to return the number of seconds since the Epoch. This avoids a call to an external utility such as date.
