All you say is true. The solution is to centralize engineering in a time zone.

It doesn't need to be a time zone in the US.

To my way of thinking, there is also a lot of communication with "requesters" (business people, designers, product managers, etc.), so they need to be in the time zone as the engineers too.

One or two hours a day of overlap seems to work fine from my experience.
