+1. I'd like to transition to a single package as much as possible,
and I think UTCTime is the right data type.

Perhaps this belongs in a separate discussion, but is there any plan
to have time provide the locale stuff directly instead of our code
needing to depend on old-locale? If I'm not mistaken, implementing
such a strategy at the same time would mean that user code could then
ignore two old-* packages.
