There are 2 options for solving this issue.
1 Change this policy to Use server time zone.
Within Desktop Studio, navigate to HDX Policy –> Users and edit Unfiltered policy, Navigate to ICA –> Time Zone Control –> Use local time of client.
2 Keep this policy and change TC time zone. If there is TCM server, you can change TCM to the right time/time zone. All TC will synch time with TCM.
