256986 Description of the Microsoft Windows registry



SYMPTOMS
You experience either of the following symptoms:  In Control Panel, when you click Date, Time, Language, and Regional Options, and then click Date and Time, you receive the following error message:

You do not have the proper privilege level to change the system time.

 Changes that you make to the time zone on the Time Zone tab do not take effect.

As a result, you cannot set the date, time, or time zone on your computer.



CAUSE
By default, only administrators and power users can change the date, time, or time zone.



RESOLUTION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To resolve this issue, ask a member of the Power Users or Administrators administrative group for the local computer to assign you the necessary user right to change the time or date and to set the time zone. To do this, administrators must grant the Change system time user right, and then add the following permissions on the  registry key:
 * Query Value
 * Set Value
 * Create Subkey
 * Enumerate Subkey
 * Notify
 * Read Control



STATUS
This behavior is by design.



MORE INFORMATION
The system user right, SeSystemtimePrivilege, controls the ability to set the system time. Changing system time is a security-sensitive user right that affects the reliability of auditing, and is also used in Kerberos version 5 protocol negotiation. The default policy assigns SeSystemtimePrivilege to the Administrators and the Power Users groups. Time zone information is not security-sensitive, but it is a system-wide setting. By default, only members of the Administrators or the Power Users groups can change time zone information.
