Same date.
A star for wolfgang! The answer is 48 hours.
The day begins when it's midnight just to the west of the International Date Line.
Midnight then moves westward one time zone every hour, continuing to start the
same day in new locations for 24 hours. The last place the day will begin is just
east of the Date Line, after which the day will take an additional 24 hours to end.

So a carefully placed and timed step doubles the calendar day-length? I feel violated by this puzzle. If we follow the sun, the day never ends.

Your answer is 49 hours! Not 48.
It doesn't matter how straight the Date Line is. There are 24 time zones globally.
Starting and ending in the time zones immediately to the west and east of the
Date Line are what's important. Check it on a map.

Which statement do you not understand or disagree with?
You added time by changing location. Adding time was forbidden by the op.
