Think about what would happen if someone was actively using a Magma
database during a "fall back" daylight savings time transition period.

That is a separate topic. In UTCDateAndTime I changed the instance variables
in DateAndTime, which requires considering what to do with "old format"
instances that may be stored in a snapshot.bin and need to be materialized
while processing the Monticello update stream that I prepared for UTCDateAndTime.
I added the necessary support recently, but I will need to rebuild the update
stream is there is interest in using it.
