In control panel (find it by clicking in the search box), display it as large icons, then choose date and time. It is a completely different screen, and as far as I can tell, the only way to access time changes. The third tab (Internet time) is the one you need. You choose "change settings" and uncheck the box that allows it, then click on the apply or OK at the bottom.
