Websites can discover your time zone in two ways.

  • The first one is by running your IP address through an Ip2Geo database.
  • The second way is by using a JavaScript function that reads time zone through browser API from regional settings of your operating system.

Websites then check whether the results of these two 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 the system time zone retrieved through JavaScript to the proxy location. In Multilogin this can be done on a browser profile level either automatically or manually. 

Automatic Timezone selection

When the option "Fill timezone based on the IP" is enabled, before a browser profile is launched, Multilogin will 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. Multilogin 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 also be 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. Manual set up can be useful when connecting to a proxy that returns IP-dependent data (a detailed solution is described in this article).

To set timezone manually, please first check your proxy IP on
