time command


When running the command 'time' it gives:

real 0m0.161s
user 0m0.070s
sys 0m0.070s

What actually is user time and system time? I don't understand the difference. Can someone explain? Thanks!

Code:
TIME(1)                

NAME
     time - time command execution

SYNOPSIS
     time [-al] [-h | -p] [-o file] utility [argument ...]

DESCRIPTION
     The time utility executes and times the specified utility.  After the
     utility finishes, time writes to the standard error stream, (in seconds):
     the total time elapsed, the time used to execute the utility process and
     the time consumed by system overhead.
Courtesy of `man 1 time`

Ahh thanks. My 'man time' didn't show that kind of description. Thank you!

Indeed. I should have mentioned that the description I posted was from a BSD machine. The reason I posted it was, like you, when I read the Linux man page for time I saw that it sucked
