There's a few ways to do it: as you can see, I like to use the 1/100 as the base unit (it's a little under 15 minutes in current reckoning) and go decimal beyond that since you have a neat percentage as a result, and you can drop off precision as needed.
We often (jokingly) measure time in kiloseconds around my office. As rue points out, that's just a bit over fifteen minutes, so its actually a useful unit.

Put a bunch of geeks together too long and this is what happens.
