I work as part of a mostly American dev team, but out of Sydney. We vary between having team meetings at my midnight, which includes the US East, but doesn't include the US West, or 8-9am, which can include the US West but not the east. The former becomes 2am with Aus moving one way and the US East moving the other, at which point I stop having any real contact with the US East.
