I cannot edit my time zone

If you cannot edit a time zone, typically, it is because you do not have the proper authority.

Recovery steps

To edit a time zone, you must have change (*CHANGE) authority to the time zone object. Each time zone is initially created with public use (*USE) authority, not change (*CHANGE) authority, even if you create a time zone based on a time zone with a different authority. However, if a time zone is created using a CL command, you can specify an authority other than public use (*USE) authority.

If you do not have change (*CHANGE) authority and need to edit a time zone, a system administrator or user with change (*CHANGE) authority and object management (*OBJMGT) authority needs to give you authority. The public can be granted change (*CHANGE) authority or only you can be granted authority by specifying your user name.

To change the authority level, a system administrator or user with change (*CHANGE) authority and object management (*OBJMGT) authority must complete the following steps:

From System i® Navigator, expand My Connections > system-name > Configuration and Service > Time Management > Time Zones.
On the Time Zones dialog, highlight the time zone you want to edit.
Click Edit.
On the General page, click Permissions.
On the Permissions dialog box, select change (*CHANGE) authority for the public or click Add to grant a specific user change authority.
Edit the Permissions as necessary.
Click OK to close the Permissions dialog.
Click OK to close the time zone properties.
Click Close to close the Time zones dialog.

Note: If you want to edit one of the IBM-supplied time zones, you should create a new time zone based on the existing time zone. This prevents your changes from being lost when you install the IBM® i operating system in the future.
