How to calculate time zone?

You have to divide the longitude, in degrees, by 15 to find the appropriate time zone, in hours. For example: At 150 degrees west (or 150° W) longitude, the time should be 150 degrees divided by 15 degrees = 10 hours behind UTC, or UTC-10.

How to calculate UTC time?

Add the local time offset to the UTC time. For example, if your local time offset is -5:00, and if the UTC time is shown as 11:00, add -5 to 11. The time setting when adjusted for offset is 06:00 (6:00 A.M.). Note The date also follows UTC format.
