Time Zone Table

Click here for a World Map of Time Zones from the USNO.

In the new NOAA solar calculators, we have changed our time zone definition to conform with the standard, which is the number of hours to add to UTC to get local time. Please note that if you use the old calculators (those without the Google Maps interface), you will need to reverse the sign (+7 becomes -7) from the numbers in this table.
