I don't like that idea. Backward compatibility with an 11 year obsolete version that produces wrong answers for a 1 year old version is not the right tradeoff. If 24:00:00 produced error messages in a version of zic that was, say, 3-4 years old, that would be different. But I can't see any reason to accommodate a version that's 11 years old. So make it 24:00 and let people know they need a version of zic that isn't antique. paul
