Websites can discover your time zone in two ways. First is by running your IP address through an Ip2Geo database. The second way is by using a Javascript function which reads time zone through browser API from regional settings of your operating system. Websites then check whether results of two mentioned checks match. If they don’t it is likely that you are using a proxy server located in a different time zone than your computer. 

Therefore, it’s vital for your privacy to match system time zone retrieved through Javascript to the proxy location. In Incogniton this can be done on a browser profile level either automatically or manually. 

Automatic Timezone selection
When an option “Fill timezone based on the IP” is enabled, immediately before a browser profile is launched, Incogniton will first try to connect to its own servers through a connection that you set up in browser profile settings. After a successful connection, the backend will see your actual external IP address, the same address other websites will see.

Incogniton will then retrieve the corresponding timezone for this IP address from a continuously updated Ip2Geo database and set it in for the browser profile. This timezone will be used while the browser profile is opened.

Manual Timezone selection
Timezone can be also set manually. By disabling “Fill timezone based on the IP” you get access to the manual configuration form. You may then select the desired Timezone value from the list of standardized Unix Timezone values.
