> ex. Time zone is more specific and stable Time zone is also much less useful for fingerprinting because it's tightly correlated with other signals like IP location and language preference. If you already know that a user's IP is somewhere in California, the additional information that they're using the Pacific time zone adds little value. (If a user's time zone doesn't agree with their geolocation, that's certainly a signal -- but it's going to be an uncommon one.)
