Show the answer

Correct answer: b) The same zone time, but those in East longitude are one day ahead of those in West longitude.

Why it is correct

Time zone 12 is split into two 7.5° half-zones by the 180° meridian (International Date Line): −12 in East longitude (UT + 12 h) and +12 in West longitude (UT − 12 h). Both show the same clock hour, but places in East longitude are one calendar day ahead of those in West longitude.

Why the others are not

  • a) They differ by 24 hours (one calendar day) on either side of the 180° meridian.
  • c) It is the other way round: East longitudes are ahead of Greenwich and one day ahead of West longitudes.
  • d) Option b) is correct.

How to work it out in the exam

  1. Zone 12: same clock hour on both sides of 180°, with East longitude one day ahead of West.
