Question 1 of 27070

You are in LONG 144? E. The date is 6 February, and the zone time is 0800. The Greenwich date and time are __________.

🔍 Key Concepts

• How to convert longitude to zone description (ZD), including the sign (east vs. west of Greenwich) • Relationship between zone time (ZT), Greenwich Mean Time (GMT/UT/GHA), and zone description • How date changes when you cross the International Date Line / 180° meridian in time calculations

💭 Think About

• Determine the correct zone description (ZD) for 144° E. Is it plus or minus, and what is its numerical value in hours? • Use the basic relation G.M.T. = Z.T. ± ZD. In this case, should you add or subtract the ZD to go from local zone time to Greenwich time? • After adjusting the time by the ZD, check whether the clock time passes midnight. Does that move the date to the previous day or the next day in Greenwich?

✅ Before You Answer

• Confirm that each 15° of longitude = 1 hour difference in time • Confirm the correct sign of ZD for east longitudes before doing the math • After you compute GMT, re-check both the hour and the calendar date before matching to the choices
