Two Days and Five Minutes Later
Sarah and Mike conclude that it is Wednesday. But five minutes later it is already Friday. How is that possible?
it is wednesday night at 11:57 and they are walking west, just shy of the international date line... 5 minutes later (in the new time zone), it is friday.
would that still work even though they would walk over a time zone boundary as well? they would have to start walking at 12:57 in order to be at 12:02 five minutes later. however, that would not be wednesday to friday. it would be thursday to friday instead. ?

They are discussing what day it is the day before on Thursday 11:55pm. 5 minutes later it's Friday~ :)
