Update child formatters for large clock with correct time format

Root cause was Ic522121ba8de7374caa0120e2c07ee2ca8e314ab which was
intended to dedupe Calendar and SimpleDateFormat. The formatters are
only partially shared and as a result a couple of additional objects
weren't correctly receiving the updated time format.

While it shouldn't be nessecary (as the calendar is fully shared) I'm
also defensively adding a similar update to TimeZone to ensure it's
correct when refreshing the time immediately after a change.
