Why are you using jiffies for timestamps?  I guess these values
are measured "since bootup" or something like that?

Anyways, I prefer the "too much math" because 1) it isn't a lot of
math, most of these things are constants which make the expressions
easy to compute 2) it's only done when someone asks for the information.
