                     12: .B time
                     13: [-l] command
                     14: .SH DESCRIPTION
                     15: The given command is executed; after it is complete, \fItime\fP
                     16: prints the elapsed time during the command, the time spent in the
                     17: system, and the time spent in execution of the command.  Times are
                     18: reported in seconds.  If the \fB-l\fP option is supplied, the
                     19: contents of the \fIrusage\fP structure are printed as well.
                     20: .PP
                     21: On a PDP-11, the execution time can depend on what kind of memory
                     22: the program happens to land in; the user time in MOS is often half
                     23: what it is in core.
                     24: .PP
                     25: The times are printed on the diagnostic output stream, ``stderr''.
                     26: .PP
                     27: \fITime\fP is a built-in command to \fIcsh\fP(1), with a much different
                     28: syntax.  This command is available as ``/bin/time'' to \fIcsh\fP users.
                     29: .SH BUGS
                     30: Elapsed time is accurate to the second, while the CPU times are measured
                     31: to the 100th second.  Thus the sum of the CPU times can be up to a second
                     32: larger than the elapsed time.
