Question 1742Navigation General

The correct answer is B) It is 1000, 7 July. When crossing the 180th meridian (International Date Line) while traveling westward, the local date changes to the next calendar day. Since you are crossing the 180th meridian at 1000 zone time on 6 July, your local time will be 1000 on 7 July. The other options are incorrect because: A) Crossing the 180th meridian westward means the local date advances, not goes back a day. C) The local date changes to the next calendar day, not staying the same. D) The time is 1000, not 2200.
