UTC/GMT Clock Calculator

In order to reduce the load on the server and also reduce bandwidth traffic, we have modified our original display so that the clock is based on our server clock, no longer the U. S. Naval Observatory Atomic Clock. Different methodologies and views are available in our International Time Display and in our International Time Zone Converter. You can also view our International Time Zone Map.

This converter requires the use of Javascript enabled and capable browsers. UTC, Coordinated Universal Time, popularly known as GMT (Greenwich Mean Time), or Zulu time. Local time differs from UTC by the number of offset, + (TO) or - (FROM), hours of your timezone. Offset times that are + (or no indication) are added TO the local time to yield UTC. Offset times that are negative are subtracted FROM the local time to yield UTC.
