Greenwich Mean Time (GMT) was historically the noon time when the sun crossed the Greenwich Meridian in the UK.
Although technically this is no longer the case, it is still refered to as the arbitary time from which the other times are derived and is the global time standard.
Standard time would vary and I must assume that this the 'standard' time where you live. So if you live in Dallas, TX you'd be GMT + 6; i.e. you are running 6 hours behind Greenwich.
Central Standard time is GMT -6 Central Daylight Time GMT -5
Saudi Arabia is three hours ahead of GMT (GMT +3)
GMT (Greenwich Mean Time) is eight hours ahead of PST (Pacific Standard Time or Pitcairn Standard Time).
the time difference is 5 hours behind our time ( London ) e.g If it was 9 am in England it would be 4 am in New York
India Standard Time (IST) is 5:30 hours ahead of GMT.
Arizona does not observe daylight saving time, so it is on Mountain Standard Time (MST) all year round. During daylight saving time, GMT is 7 hours ahead of MST. When Arizona is in standard time, GMT is 7 hours ahead.

The time difference between Greenwich Mean Time (GMT) and Canada varies depending on the region within Canada. For example, Eastern Standard Time (EST) is GMT-5, Central Standard Time (CST) is GMT-6, Mountain Standard Time (MST) is GMT-7, and Pacific Standard Time (PST) is GMT-8. Canada spans multiple time zones from GMT-3.5 in Newfoundland to GMT-8 in British Columbia.
5 hours. Example: 9 AM Eastern Standard Time {EST} = 2 PM Greenwich Meant Time {GMT}
