I am with Phill here. Assuming we have no requirement for round tripping (we can debate that seperately if you wish) I don't think there is a problem.

No matter how we represent it in XML it will have to be represented internally somehow. As long as this conversion does not change a less than relationship into a greater than relationship  or vice versa, I don't see an issue. I don't see doing math on the a seconds field of a date/time. I realize that 2.99999999999999999 might end up equal to 2.99999999999999998, but this will also happen if we limit the precision.
