A closely related issue: fromIntegral is in Integral which also requires quotRem. However, the two are semantically quite disjoint. I can *easily* see the semantics of fromIntegral on EpochTime, but not the semantics of quotRem on EpochTime. Having fromIntegral would solve the above puzzle... :)
As I understand it, it's widely recognised that Haskell's current numeric class hierachy is broken (or at best, not very well chosen), but nobody came up with a better suggestion yet.
Oh, there are /lots/ of suggestions. Perhaps too many. But this is one area that could really be improved by the use of ATs or MPTCs with fundeps, and that's stalled some of the concrete proposals, as what exactly is happening for Haskell' isn't too clear. -- Aaron Denney -><-
