This puts us back to having the extra DateFormat that Vijay wanted to avoid by
having the named constructors. Maybe we should support new DateFormat.hms()??

These tests clearly won't run because they use DateFormat and it was renamed,
but I presume that comes as part of the TODO at the top.

   });
