World wide time zone table

There are 24 time zone regions worldwide. Each region's time is calculated by how close it is to the UTC (used to be known as the Greenwich London or GMT). The UTC is a commonly agreed on imaginary line and was first developed in the 1800 in order to standardize a method of telling time world wide. Back then it helped make traveling and communication much easier. Now that working virtually is more and more common, keeping track of these differences become much more challenging! Take a look at the time zone converter and World clock page to convert time without the math.
