This is a list of the UTC time offsets, showing the difference in hours and minutes from Coordinated Universal Time (UTC), from the westernmost (−12:00) to the easternmost (+14:00).
Map of U.S. time zones with new CST and EST areas displayed. Some U.S. time zones, such as the Samoa Time Zone, are not on this map. This is a list of the time offsets by U.S. states, federal district, and territories. For more about the time zones of the U.S. see time in the United States. Most states are entirely contained within one time zone.
The Pacific Time Zone (PT) is a time zone encompassing parts of western Canada, the western United States, and western Mexico. Places in this zone observe standard time by subtracting eight hours from Coordinated Universal Time (UTC−08:00).
Before the adoption of four standard time zones for the continental United States, many towns and cities set their clocks to noon when the sun passed their local meridian, pre-corrected for the equation of time on the date of observation, to form local mean solar time.
The UTC offset is the difference in hours and minutes between Coordinated Universal Time (UTC) and the standard time at a particular place. [1] This difference is expressed with respect to UTC and is generally shown in the format ±[hh]:[mm], ±[hh][mm], or ±[hh].
The numeric zone description or "plus and minus system" indicates the correction which must be applied to the time as expressed in order to convert to UTC. For example, the zone description for the Romeo time zone is +5. Therefore, adding 5 hours to 0600R produces the time in UTC, 1100Z. [1]
