           15 .SH DESCRIPTION
           16 If
           17 .I t
           18 is non-null,
           19 .I times
           20 fills it in
           21 with the number of milliseconds spent in user code, system calls,
           22 child processes in user code, and child processes in system calls.
           23 .I Cputime
           24 returns the sum of those same times, converted to seconds.
           25 .I Times
           26 returns the elapsed real time, in milliseconds, that the process has been running.
