I had the "timezone thing" with a colleague in the same city because he had some weird sleep disorder. Basically, he was a vampire. Asleep during the day, working all night.

It was awesome. I'd turn up to the customer site to collect their issues and requests, do some investigation, formulate the precise requirements, and send it off to him.

The next morning, magically, things would be done.
