This AO is required for a bunch of PlainTime related methods. As part of this change the `TemporalTime` record was renamed to `UnregulatedTemporalTime` and a new `TemporalTime` record that matches the other Temporal parse result records was added. This also has the added benefit of getting rid of a would be round-trip cast from integer to double and back in `ParseTemporalTimeString`.
