Isn't it just an integer? i also found this problem when switching from 6.2.2 to 6.4, but found some way to walk around it. what is your actual problem? i think that ctime is no more an Integral because you can't add CTime+CTime, nor multiple CTime*CTime and so on - just to catch some possible bugs. but it can be converted to Integral, see at this: modificationTime :: Ptr CStat -> IO ClockTime modificationTime stat = do mtime <- st_mtime stat let realToInteger = round . realToFrac :: Real a => a -> Integer return (TOD (realToInteger (mtime :: CTime)) 0) -- Best regards, Bulat mailto:bulatz@HotPOP.com
