There are four/six different time zones. There is the Eastern, Central, Mountain, and Pacific Time Zones and Hawaii and Alaska each have their own time zone. Parts of Alaska, the Aleutian Islands, do use the Hawaii Time Zone.
The United States spans 6 time zones. It shares the main four time zones with Canada which are Eastern Time , Central Time, Mountain Time and Pacific time. Hawaii Time and Alaska Time are separate Time zones
At any given time, the clocks around the world are set to at least 38 different times, and these time zones have about 165 different names, including about 130 different names just for Standard Time designations.
Time zones were crested to have the local time correspond with the amount of daylight hours there are. The sun sets and the daylight hours fade at different times in different places. With time set up to correspond with this it creates different time zones.
There are different time zones because since the Earth rotates, different places get sunlight at a different time. If there were no time zones, 11:00 am would be near noon in one place, near midnight in others, and some places evening and early morning.
The United Kingdom has only one time zone in their area. This time zone is called the Greenwich Mean Time, this is because the United Kingdom is smaller than other areas and does not need different time zones for the amount of land that it is made up of.
Its because time is calculated with the help of latitudes and longitudes. one country can also have many time zones if its latitudes and longitudes are capable of creating them :) -Hrijul Bhatnagar (The Known Scientist)
Well, seeing as they all are completley different worlds, and there is really very small similarities between the days and nights, it is mostly common sense that no. They do not have the same time zones. Yes, universes have different time zones. They are a completley different world (So to speak)
