Are you running XP Pro or Home? For XP Pro, this can be restricted via the Group Policy Editor (Start, Run and enter GPEDIT.MSC). Go to:
Go to Computer Configuration, Windows Settings, Security Settings, Local Policies, User Rights Assignment.
By default the Administrators and Power Users groups have this privilege. You can edit this so that only specific users have this privilge.
For XP Home, you would have to restrict access to the TIMEDATE.CPL application.
To do this, you must be running NTFS as your file system on the drive in question. If your hard disk/partition is not NTFS you will need to convert it. To do this, open a Command Prompt window and enter the following command:
CONVERT X: /FS:NTFS
Where X: is the drive letter you wish to convert. You may also want to see http://www.aumha.org/a/ntfscvt.htm to ensure that you're getting the optimal conversion.
After this step is completed and you've rebooted the computer, if necessary:
XP Home: By default, you can only make files and folders under My Documents "private". This is done by right clicking a folder or file and selecting Properties, Sharing. To change the permissions on other folders, you need to boot the computer to Safe Mode and log in on the built in Administrator account. In this mode, you'll see the Security tab in Properties, and you can assign permissions based on user name or group membership.
