I always end up with a wrapper around it, taking a NominalDiffTime; I could never be sure whether threadDelay interpreted its argument as milli-/micro-/nano-seconds without looking it up.
I too always end up with a wrapper, but my wrapper takes a Double, which is in seconds. Seconds are easy, and a Double means that you can specify ridiculously long intervals, and for short intervals you have high precision. I find it much easier to write sleep 5, when I want to sleep for 5 seconds, than putting in some multiplication factor.
Note that NominalDiffTime has all the necessary instances to able to do the same. I.e. (5 :: NominalDiffTime), (5.123 :: NominalDiffTime), or (10^100 :: NominalDiffTime). These numbers are also interpreted as seconds, with a precision up to 10^-12. Erik
