After installing Citrix VDA, a security audit might reveal the "Change the system time" user right assignment has been granted to NT SERVICE\BrokerAgent.
Find this permission at Computer Configuration > Windows settings > security settings > Local policies > User Rights Assignment [ Change the system time ]


This permission is expected on the installation of the Citrix VDA. The permission is required to support Time zone control policy settings.
