which one of the following cities does not have the same clock time as that of the other three cities at any given instant?

1. Clock time is determined by time zones, which are generally based on lines of longitude. 2. London (U.K) is on the Prime Meridian (0° longitude) and typically observes GMT (or BST in summer). 3. Lisbon (Portugal) is also in the Western European Time Zone (WET), which is equivalent to GMT (UTC+0). 4. Accra (Ghana) is geographically close to the Prime Meridian and observes GMT (UTC+0) year-round. 5. Addis Ababa (Ethiopia) is located in East Africa, at roughly 38° East longitude. It observes East Africa Time (EAT), which is UTC+3. 6. Therefore, Addis Ababa does not have the same clock time as London, Lisbon, and Accra.
