--------------------------------------------------------------------
A major concern is that the clocks are part of the API and schema. So if we
commit this as-is then we have several possible scenarios:
1. clock change gets in before 0.7.0 and everything is fine
2. clock change isn't ready for 0.7.0 and we block 0.7.0 for it
3. clock change isn't ready for 0.7.0, we release anyway, and break
compatibility w/ the next release
4. clock change isn't ready for 0.7.0 so we postpone it until 0.8 (thus having
to maintain both versions until 0.7 is obsolete)
2-4 are not acceptable and while I know you have the best of intentions to
finish it right away, the rest of 0.7.0 is shaping up rapidly and it just
doesn't look like a good risk to me.
