Only partially reviewed, but I think the tz handling is fragile and should probably be fixed. I expect that the dev machines will show incorrect times on migrated data. (If not, then I must be mistaken in my comments.)

[jennifer-richards]

A few comments - I think the tz stuff is still in need of changes.

The n+1 business looks good to me, but I'm still thinking about how it can be made more maintainable.

[jennifer-richards]

My concerns are addressed.

I'm a little uneasy about the monkey patched optimizations - it'd be nice to find a better pattern for that. I don't see a reason to hold this up for solving that, though.
