command
by initiating a timer and passing the

and the time used to execute the
command
process.

The
csh(1)
has its own and syntactically different builtin version of
time.
The command described here

users.
BUGS
The granularity of seconds on micro processors is crude and
can result in times being reported for CPU usage which are too large by
a second.
