normalizeTimeDiff (and TimeDiff in general) is wrong. I wouldn't recommend using it. There's the TimeExts library in the lang package, which might be useful to you.

I'm curious about that package. It's in my ghc source tree but not documented at http://www.haskell.org/ghc/docs/latest/html/libraries/index.html.

Is it assumed to be portable and available outside ghc?

It's an old non-hierarchical library, unfortunately with no documentation. It'll probably disappear in GHC 6.6, but you can always take the source and use it in your apps. Hopefully by 6.6 there will be a decent date/time library that provides this functionality. Cheers, Simon
