Answer:
Here is your answer:
Explanation:
If all time zones aligned perfectly with the 24 lines of longitude that are 15 degrees apart (beginning with zero longitude at the Greenwich Meridian), then the time at 30 East would be exactly four hours later earlier than the time at 30 West, i.e. 6 pm. (See the map from https:/wp-content/uploads/2016/03/time-zone-map.jpg, below).
However, the official time zones (see “”, at the bottom) do not follow the longitudinal boundaries, so different places at 30E are in different zones, as are different places at 30W.
The 30W longitude goes thru Greenland, where the time is 3 hours earlier than GMT (or UT, if you prefer); however it also goes thru points near the Azores where the time is only 1 hour earlier, as well as South Georgia where the time is 2 hours earlier (not to mention Grand Banks of Newfoundland, where time is three and a half hours earlier!)
The 30E longitude goes thru Finland, Greece, Egypt, Congo, and South Africa (as well as Estonia, Latvia, Lithuania, and near Koenigsberg/Kalingrad) where the time is 2 hours later than GMT, but it also goes thru Belarus, Turkey, and Uganda where the time is 3 hours later, as well as the northern tip of Norway where the time is only one hour later than GMT.
Therefore, it is possible for two people at 30W and 30E to have clocks that differ by various amounts. For example, if it is 2 pm for someone at 30 W in Nanortalik (formerly Nennortalik), then someone at 30 E might have an accurate local clock that says 6 or 7 or 8 pm. However, if it is 2pm in the Azores or near South Georgia, then those 30 E clocks would be different by 1 or 2 hours, and if the 30 W clock was near Newfoundland, then the minute hand would be off by another half-hour!
Fortunately, you haven’t asked about longitudes like 60 E or 90 E (thru Iran, Afghanistan, India, or Burma) where clocks are also 1/2 hour off, not to mention desert places (like Saudi Arabia or the Sahara) where local time depends upon where the sun is in the sky! If places like Adak or Samoa or the Minerva Reefs are involved, then the clocks might differ by more than 24 hours and the calendar would show a different day (or year!)
