Describes the best practices, location, values, policy management, and security considerations for the Change the time zone security policy setting.

Policy management

A restart of the device is not required for this policy setting to be effective.

Any change to the account for this user right assignment becomes effective the next time the account logs on.

Group Policy

Settings are applied in the following order through a Group Policy Object (GPO), which will overwrite settings on the local computer at the next Group Policy update:

  1. Local policy settings
  2. Site policy settings
  3. Domain policy settings
  4. OU policy settings

When a local setting is greyed out, it indicates that a GPO currently controls that setting.

Security considerations

This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.

Vulnerability

Changing the time zone represents little vulnerability because the system time is not affected. This setting merely enables users to display their preferred time zone while being synchronized with domain controllers in different time zones.

Countermeasure

Countermeasures are not required because system time is not affected by this setting.

Potential impact

None.
