🔍 Key Concepts

• Relationship between Greenwich Mean Time (GMT) and zone time • How to apply a zone description (ZD) like -13 to convert between GMT and local time • How changing time across large offsets can also change the calendar date

💭 Think About

• First, decide whether a negative zone description means the local time is earlier than or later than Greenwich time. • Calculate how many hours you must add or subtract when going from GMT (ZD 0) to a zone with ZD -13. • After adjusting the time, check whether you have crossed midnight, and then determine if that moves you to the previous or next calendar date.

✅ Before You Answer

• Be clear whether you are converting from GMT to zone time, or from zone time to GMT. • Carefully handle the sign of the ZD (-13): does it mean GMT = zone + ZD, or zone = GMT + ZD? Write the formula both ways and pick the one that matches the definitions you’ve learned. • After you get the local clock time, verify if the resulting time falls on the same date, the previous date, or the next date compared to 10 January.
