Find out the longitude of your location in degrees, multiply by 24 and divide by 360. This gives the difference in hours between your location and the Prime (or Greenwich) Meridian. For example;
1. Longitude 10 degrees East: 10*24/360 = 0.67 hours approx., = 40 minutes.
Local time would be GMT plus 40 minutes (e.g, if the time was 11.20 GMT, local time would be 12.00);
2. Longitude 15 degrees West: 15*24/360 = 1 hour.
Local time would be GMT minus 1 hour (e.g, if the time was 11.00 GMT, local time would be 10.00).
Subtract one hour from a BST time to convert to GMT. To do the opposite, add one hour to a GMT time to convert to BST.
To convert a time given in GMT to India time, add 5½ hours.
GMT + 1 hr. = BST (spring ahead)
During summer, GMT + 1 hour. (GMT is the Wikianswers base time)
5:32 PM GMT or 17:32 UTC (coordinated universal time)
The UK and Morocco.
16:00 (Local time - [GMT +2])/ 10:00 (US Eastern time - [GMT -4]).
To convert 6:30 EST to GMT, you would simply add four hours to the EST making it 10:30 GMT.
GMT stands for Greenwich Mean Time and it is the time in London or Lisbon. Local time is the time in your current location. Therefore, if you live in Rome, which is GMT+1, the time will be one hour later than the time in London (Greenwich). In the differnet time zones, one hour is added from Greenwich all the way round the world until you get back.
It's 8 PM GMT.
You have to do a conversion to your local time. If you live in the GMT + 5 (Eastern standard time) and wish to find out when an even in GMT + 1 is at you would add four hours. It is the difference between the time zones. If you want to find out what time an event is at that is GMT - 4 you would add 9 hours, because 5 - -4 is 5+4 = 9. That is the general rule, your GMT - Other TimeZone. GMT + 5 - GMT - 4 = 5 - -4 GMT + 5 - GMT + 1 = 5 - 1 Then the result is added to the time.
