Question

what are the effects of internal dateline?

Answer 1

The reason for this effect is that the countries on the western side of the International Date Line, (in or outside eastern Asia) have the time zone 10–12 hours more than Greenwich. ... So when travelling across the line, one's watch has to be adjusted 20–24 hours, depending on the time zones.

If this helps then plzzzzz mark me brainliest.
