A ship sailed eastward near point E, 10 minutes later crossed the EF line. When should the ship be in the area?

The meridian where EF is located is 180, which roughly coincides with the date line. In the picture, there is an extreme day in the Antarctic circle, which means that this day should be the winter solstice in the northern hemisphere, that is, 65438+February 22. As can be seen from the figure, when the belt on the west side of EF meridian is 65438+2 1 on February 22, the ship sailed eastward through 180 meridian, which means that the ship entered the west side of 12 from the east, and the date will be reduced by one day. The belt where the ship arrived should be 65438+February 2 1.
