I think what I will do is start with adding/extending the tests relating
to timestamps and clock tables. This should

- help ensure I understand the required functionality
- may help identify existing bugs
- help ensure any refactoring does not have undesired side effects or
  loss of functionality

I also suspect it will be a good way for core org maintainers to verify
I'm on the right track and haven't missed anything before making any
changes to the code base. I'm not a big TDD advocate, but when working
with an unfamiliar code base, I've found developing tests first is a
good approach to ensure you really do understand existing and required
functionality.

Tim
