] [1.1 ] Hello, On my system, GHC 6.6 running on windows xp, System.Time.toClockTime fails on calendar times later than (by days, I didn't check hours, minutes, etc.) January 18, 2038. Is this a bug?
This is the famous unix epoch bug -- unix time is based on the number of seconds since some date in 1970. About 4 billion seconds later is 2038, and the counter wraps around. Try using Data.Time instead -- it was written by a self-professed time nerd, and probably works correctly. It was added in GHC 6.6 and largely supercedes System.Time. j.
