Hard to say.  Those bugs might affect the way a stored timestamp would be
printed, but I don't really care to do the legwork that would be needed
to identify exactly what the consequences would be.  In practice, I doubt
that the effects would be much different from a change in DST law that
might happen between now and 2037 --- anybody who's predicting now what
their local DST laws will be by then is pretty far out on a limb anyway :-(
