Firstly we are talking about time deltas, and on the sysctl side of things
it's very hard to set 'timevals (as you'd need to set two different
variables) so you need a single value on teh userland side of things.
Inside the kernel it's all done in ticks, so you should store that.
thus having chosen the two units for internal and external, the function
almost defines itself.
