Windows 10 is one of the most customisable operating systems on the market, allowing for an almost endless number of changes to be made across the entire operating system. It's possible to block access to just about any area or feature you want. Though each change requires very specific adjustments to be made in some of the operating systems most sensitive areas. 

Thankfully if you need to make sure that nobody can fool around with the time or timezone on your computer you won't need to make any drastic changes, you simply need to access Local Security Policy (LSP) settings. Within LSP there are a range of different options that allow you to restrict certain parts of the operating system, however, you'll want to make sure you don't go changing anything by accident as you may cause major security issues.
