Windows XP Home/Professional: Standard users ("Users") do not have the ability to change the system time. Only "Administrators", "Power Users", and "LOCAL SERVICE" have this ability.
If you wish to modify this further with Windows XP Professional you can use the Group Policy Editor (gpedit.msc). The setting is located under Computer Configuration, Windows Settings, Local Policies, User Rights Assignment, "Change the system time".
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
