Why a browser reports a time zone

A time zone converts Coordinated Universal Time into local civil time and includes rules for seasonal clock changes where they apply.

Websites use the browser time zone to format dates and times. It may differ from the location estimated from an IP address, for example after travel, manual configuration, or use of a remote device.
