By default Terminal Server keeps track of time according to the time zone in which it has been configured, rather than on a per-user basis. This can be a problem when a user connects to a terminal server outside of the time zone in which the user is located because the local computer uses the time configured on the terminal server rather than the local time. If you are hosting time-sensitive applications on your terminal server or if you have processes in place that depend on the user’s current local time, such as financial systems and calendaring, you might want to enable the Allow Time Zone Redirection Group Policy setting. This policy is located in Windows Components/Terminal Services. With this setting enabled, Terminal Services uses the server base time on the terminal server and the client time zone information to calculate the time on the session.
