The Difference Between GMT and UTC:
- UTC is a time standard that forms the base of time zones worldwide and is not related to any country. A time zone in any country is defined by its offset {±12} from UTC. So...
- a time zone in any country = UTC ± offset
- GMT is the time zone of UK= UTC + 0
- GMT = UTC
What About BST?
- During Daylight Saving Time, clocks in the UK are set forward one hour to British Summer Time (BST). So...
- BST = GMT + 1 = UTC + 1
