It is incredibly easy to arrive hours before you leave. Just fly East across the dateline (like Aus to North America).
And I've even lost a birthday flying back in the other direction. Great scheduling, that.

Or use a fast plane going west (Concorde used to take ~3h for London to NYC, and NYC is on UTC-5, so passengers on Concorde would arrive "2h before they left").
