Would someone please explain GMT (time) I understand Military time for we use that time in Hospitals, and Physicians Office and obviously the Military, but I do not know what is /and how to calculate GMT.
Following is a definition I found on the web. Even after reading it and re-reading it...I haven't a clue! .
Greenwich, England has been the home of Greenwich Mean Time (GMT) since 1884. GMT is sometimes called Greenwich Meridian Time because it is measured from the Greenwich Meridian Line at the Royal Observatory in Greenwich. Greenwich is the place from where all time zones are measured. The Greenwich Meridian (Prime Meridian or Longitude Zero degrees) marks the starting point of every time zone in the World. GMT is Greenwich Mean (or Meridian) Time is the mean (average) time that the earth takes to rotate from noon-to-noon.
GMT is World Time and the basis of every world time zone which sets the time of day and is at the centre of the time zone map. GMT sets current time or official time around the globe. Most time changes are measured by GMT. Although GMT has been replaced by atomic time (UTC) it is still widely regarded as the correct time for every international time zone.

I, TOO, READ SOMETHING ABOUT GMT BUT I COULDN'T WRAP MY BRAIN AROUND IT. WE ARE TAKING THE ALASKA CRUISE IN SEPTEMBER AND I AM TOLD TIME IS CALCULATED IN GMT, SO I'M AFRAID WE ARE EITHER GOING TO BE EARLY OR LATE WHERE EVER WE GO.
GMT is the starting point for all the time zones around the world.
In the states we have EST, CST, MST, PST etc etc. Each of these are one hour ahead or behind the other depending on which time zone you are going to or from.
Best suggestion. When you get to Alaska, check the time there, and just change your watch to that time zone. If you need to keep track of what time it is at home where you live, remember how many hours before or after, from what you changed your watch from.
Hope that helps

What cruise are you taking in Alaska, because to say an Alaska cruise is calculated in GMT only makes sense to me in the following conditions:
I assume they are saying that whatever times are posted for different things (flight arrival, departure, etc) are posted according to the local time zone for where that event takes place - which is calculated according to GMT.
Like if you take a three hour flight over three time zones, you leave and arrive at the same hour, because each local place is using GMT for reference. Does that make sense?
Leave Washington DC at 6:00 pm (cover 3 time zones)
arrive Phoenix at 6:00 pm.
I hope I am right about this, because that is what they usually do.
Paul, thanks for your reply and it does make sense. I know Alaska is 3 hours behind our time, however in some instances GMT will be used and I really wanted to understand how to calculate it. I have since talked with my Brother (Ex-Military) and he explained it to me. GMT is also called ZULU Time. Now I get it !!
Eastern Time = GMT -4 (New York)
Central Time = GMT -5 (Chicago)
Mountain Time = GMT -6 (Denver)
Pacific Time = GMT -7 (Vancouver)
Alaska Time = GMT - 8 (Anchorage)
Add one hour in the Winter: Standard Time.
Eastern Time = GMT -5 (New York)
Central Time = GMT -6 (Chicago)
Mountain Time = GMT -7 (Denver)
Pacific Time = GMT -8 (Vancouver)
Alaska Time = GMT - 9 (Anchorage)
GMT is Greenwich Mean Time. Greenwich, England is the world's timekeeper. You basically take whatever time it is in London and subtract the appropriate number of hours away from that time and you have your GMT time.
