Al ser HcG= 22 h 30 m del 10 de abril de 2020, ¿cuál es la Ho y fecha si estamos en Seychelles?When Greenwich civil time (HcG) is 22h 30m on 10 April 2020, what are the standard time (Ho) and date in the Seychelles?

Show the answer

Correct answer: d) 02h 30m on 11 April.

Why it is correct

The Seychelles lie around 55º E and keep UTC+4 year-round. Adding 4 hours to 22h 30m on 10 April gives 02h 30m on 11 April.

Why the others are not

  • a) Subtracts 4 hours as if the Seychelles lay west of Greenwich.
  • b) Adds 4 hours but fails to advance the date to the 11th past midnight.
  • c) Keeps Greenwich time unchanged and only advances the date.

How to work it out in the exam

  1. The Seychelles are in the western Indian Ocean (UTC+4).
