My intention is to get UBSAN goodness for DateTime which has uncovered some
overflow
issues in the special value handling.  I cannot easily complete fixing
these without disabling
that test during UBSAN builds.  I have already submitted a pull request
into Boost.Serialization
that runs UBSAN during the build and expect that will be enough to trigger
resolution.
