Question 1 of 27070

Some locations maintain a zone time of -13. What are the Greenwich time and date if the zone time and date are 0152, 10 January?

🔍 Key Concepts

• Zone description (ZD) and how its sign (+/-) relates local time to Greenwich Mean Time (GMT/UT) • Converting between zone time and GMT when crossing the International Date Line or changing calendar dates • Adding or subtracting whole hours from a given time and checking if the date changes

💭 Think About

• Is a zone description of -13 east or west of Greenwich, and does that make local time ahead of or behind GMT? • To get from local zone time to GMT, should you add or subtract the zone description? What does the sign tell you? • After you adjust the time by 13 hours, does the clock pass midnight forward or backward, and how does that affect the calendar date (earlier or later)?

✅ Before You Answer

• Determine clearly whether ZD -13 means 13 hours east or west of Greenwich • Apply the correct formula: GMT = ZT ± ZD (decide which operation is appropriate based on the sign convention you use) • After adjusting 0152 by 13 hours, re-check if you crossed midnight and update the date (9th or 11th January) before picking an answer
