Timestamp helper fix, Duration helper cleanup.
- The Timestamp proto does not allow for negative nanos fields, so the seconds
must be shifted and a positive nanos then applied.
- Tweak the helpers on Duration to make it clear there is no "base" time
involved.
- Update the unittests for duration and timestamp to cover positive and
negative NSTimeIntervals and what their impact is on the protos.
