Your longitude is 179°59'W. The LMT at this longitude is 23h 56m on the 4th day of the month. Six minutes later, your position is 179°59'E longitude. What is your LMT and date?
• International Date Line and how the date changes when crossing it • Relationship between Local Mean Time (LMT) and longitude (4 minutes of time per degree of longitude) • How time of day wraps around at 00h 00m when adding minutes to a time near midnight
• When you move from 179°59'W to 179°59'E, which direction across the International Date Line are you conceptually moving, and does the date go forward or backward? • If LMT is 23h 56m and you advance 6 minutes, what clock time do you get before thinking about the date line effect? • After you find the raw clock time, how does crossing the date line change only the date while leaving the local solar time essentially the same?
• Make sure you correctly handle the change from 23h 56m when you add 6 minutes and pass through midnight • Confirm how the date changes when you cross the International Date Line in this specific west/east direction • Verify that the final answer has a time close to 00h 02m and that the main difference between the choices is the date you select
