Time zone control policy settings

The Time Zone Control section contains policy settings related to using local time in sessions.

Estimate local time for legacy clients

This setting enables or disables estimating the local time zone of user devices that send inaccurate time zone information to the server.

By default, the server estimates the local time zone when necessary.

This setting is intended for use with legacy Citrix Receivers or ICA clients that do not send detailed time zone information to the server. When used with Citrix Receivers that send detailed time zone information to the server, such as supported versions of Citrix Receiver for Windows, this setting has no effect.

Use local time of client

This setting determines the time zone setting of the user session. The choices are the time zone of the user session (server time zone) or the time zone of the user device (client time zone).

By default, the time zone of the user session is used.

For this setting to take effect, enable the Allow time zone redirection setting in the Group Policy Editor. The setting is in Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Device and Resource Redirection.

If the VDA is a Desktop OS VDA running on a Server OS, configure the local user right Change the time zone to Everyone. This user right can be found in the Local Computer Policy > Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment.


In a Desktop OS, Users are included in the User Rights Assignment Change the time zone, though not in a Server OS. In a Server OS, the time zone synchronizes using the following group policy: Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Device and Resource Redirection\Allow timezone redirection. This policy doesn’t apply when the Server is not a Remote Desktop Session Host in the Server OS VDA (installed with the /ServerVDI command). In a Server OS, by default and by design, users don’t have the local right to change the time zone.
