NAME
time - time a command

SYNOPSIS
time [-l] command

DESCRIPTION
The given command is executed; after it is complete, time prints
the elapsed time during the command, the time spent in the system,
and the time spent in execution of the command. Times are reported
in seconds. If the -l option is supplied, the contents of the
rusage structure are printed as well.

The times are printed on the diagnostic output stream, "stderr".

Time is a built-in command to csh(1), with a much different syntax.
This command is available as "/bin/time" to csh users.

BUGS
The elapsed time is always zero (0).
