Hello how may I help you? Can you tell me what time zone Iceland is in? I can help you find Iceland's time zone. One moment please. Sure. Take your time. Greenwich Mean Time (GMT) is Iceland's time zone. Can you tell me what time zone Greenland is in? Part of Greenland is in GMT+1 and part of it is in GMT-0. Can you tell me what time zone Norway is in? Central European Summer Time is the name of Norway's time zone. Thanks. You have been very helpful. I am here if you require assistance later. Have a great day!
