Not all programs take more than 1 second of run time. If a program
takes 0.03 seconds of run time, and the 'wall clock' column would
give me a good understanding of what's going on if printed with
6 decimal places, why do you want to truncate it to 2 decimal places?
(It's clear that the 'CPU user' and 'CPU system' columns will not be
useful in this situation; I don't argue for 2 vs. 3 decimal places
on these columns.)
