question re time(1)

[leff at smu]

I am confused about the output of time under csh.

According to the man page, I get three numbers
  the elapsed time during the command, the time spent in the system,
    and the time spent in execution of the command

What are the other four numbers output that are apparently undocumented?

What exactly do "elapsed time," "time spent in the system"
and "time spent in the execution of the command" mean???

One of our faculty has been attempting to interpret the output of
this command when applied to running ingres and we are not clear
what these things mean.  She needs this for reporting some benchmarks
run under Ingres.
