There are four time zones in the continental United States, each separated by one hour. Some of zone records use 3 or 4 letter abbreviations that are tied to physical time zones, others use numeric UTC offsets.The United States is a wide country with seven time zones. Time zone abbreviations for both Standard Time and Daylight Saving Time are shown exactly as they appear in the database. This table does not attempt to document any of the historical data which resides in the database. The UTC offsets are based on the current or upcoming database rules. Standard Time ( STD) and Daylight Saving Time ( DST) offsets from UTC in hours and minutes.įor zones in which Daylight Saving is not observed, the DST offset shown in this table is a simple duplication of the STD offset. Historical data for such zones is still preserved in the source code, but it is not included when compiling the database with standard options. The dagger symbol (†) signifies that the zone was canonical in a previous version of the database.
