If you set privacy.resistFingerprinting (RFP) to true in about:config you probably noticed that the date/time is off by a couple of hours on all websites if you don't happen to live in the UTC timezone.

The add-on fixes this by changing the offset, either user defined or by timezone, to match your local time.

This has the added benefit that you don't have to give away your real timezone which can be used to predict your location.

Works on Desktop and Mobile (only tested in Fenix)
