datetime - Basic date and time types - Python 3.9.6 documentation

Only one concrete class, the class, is supplied by the module. The class can represent simple timezones with fixed offsets from UTC, such as UTC itself or North American EST and EDT timezones. Supporting timezones at deeper levels of detail is up to the application.
