Uptime

[Andrew Pritchard <andrew@teppic.co.uk>]

>From the Man page:
   uptime  gives a one line display of the following informa­tion.
   The current time, how long the system has been run­ning, how 
   many users are currently logged on, and the sys­tem load 
   averages for the past 1, 5, and 15 minutes.

What exactly does the 'load averages' mean? Is it the CPU time?

Just for my own curiosity really

Cheers,

Andrew
