Hmmm, that's right. Perhaps it would be best to use some fixed-point type with unbounded integral part, like those used for representing currency, but not necessarily decimal.
I'd go with ratios. Haskell has a built-in type, and they can give you as many digits of precision as you need--unless you're dealing with an irrational timeout value.
Unfortunately, they have the unpleasant tendency that after many operations even if the absolute value is small, the two integers that constitute the ratio can be very big. That's why (I think) it's not that good idea to solve linear equation systems using unbounded ratios. Why not use typeclasses and let the user decide?
