Has anyone built Ashley's Data.Time package on Windows? I ask because timestuff.c fails to compile for me because it refers to fields (tm_zone, tm_gmtoff) in struct tm which don't seem to exist on Windows (at least, mingw).

Yes, I made it work on Windows recently. The fixes should be in the darcs repo at http://darcs.haskell.org/packages/time, did you get it from there? Cheers, Simon
