Having a ceil method is usefull for cases where you have a minimum duration, but in reality it needs to be on a per X basis, so the duration might only be 0.5 seconds, but in-reality it can only finish once aa second so you want to round it up to 1 second.
The Time package provides a time round method for rounding to the nearest X and a truncate method for rounding down(towards 0) but not the other way around (away from 0) making it incomplete.
