Amos-

What's a decimal point or two?

But the intriguing question is how fast must we fly to go back in time, or do we just end up encountering the sunset of the next day as we cross the International Date Line? And would it make any difference which direction we traveled, East or West?

I'll go away now while you and others ponder these inscrutables.

Cheerily,
