?? I think we agree. It happens to be the case that slightly incorrect
results are wrong results, and that full IEEE math conformance gives
exactly correct results. For the case of date/time, the "slightly wrong"
results round up to 60.0 seconds for times on an even minute boundary,
which is just plain wrong.
