This report shows the user CPU time, system CPU time, the sum of the
user and system CPU times, and the elapsed real time. The unit of time
is seconds.

i.e. time spent in user mode, kernel mode, user+kernel (for these only
time spent by this particular program is counted) and elapsed real
("wallclock" time)
