Citrix Virtual Apps and Desktops

Time zone control policy settings

The Time Zone Control section includes 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. These devices include the 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. Consider that this setting is used with Citrix Receivers that send detailed time zone information to the server. For example, supported versions of Citrix Receiver™ for Windows. In this case, this setting has no effect.

Restore desktop OS time zone on session disconnect or logoff

Consider that the user disconnects or logs off a session. In this case, this setting determines whether the time zone setting for a Single-session OS VDA is restored to the machine’s original time zone. If you enable this setting, the VDA restores the machine’s time zone to its original setting when the user disconnects or logs off. For this setting to take effect, set the Use local time of client to Use client time zone.

By default, this setting is enabled.

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 in multi-session session hosts, 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.

IMPORTANT:

When using the single-session VDA version 2507 on machines running a server OS, you must add Users to the Change the time zone User Rights Assignment policy. This policy is located under Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment. This is not required when using version 2507 CU1 or later.

When using the single-session VDA version 2507 CU1 and later, the Citrix Portica Timezone Service (CtxPicaTzSvc) is automatically added to the Change the time zone User Rights Assignment policy during the VDA installation. If you have any policies or processes in place that remove users or processes from these policies, make sure to modify them so that the Citrix services are not removed. Otherwise, time zone redirection will not work.
