What is the difference in time between time zones?
Time Difference from UTC :
UTC time changes 1 hour forward and backward corresponding to a 1-hour difference in mean solar time for every 15 degrees east or west of the prime meridian (0° longitude) in Greenwich, London, United Kingdom.
The offset is expressed as either UTC- or UTC+ and the number of hours and minutes.
Each time zone is 15 degrees wide and there's a one hour difference between each one.
Depending on the distance -- east or west -- from the Greenwich Meridian you must either add or subtract the appropriate time for every 15 degree interval.
