Hi,
There are two ways that administrators prevent users from changing the date and time of their system.
In case we need to do the needful on a system with multiple users, it could be done through the Registry Editor. Otherwise, administrators managing multiple systems with the group-policy editor could also restrict users from changing the date and time through the group policy editor.

Hope above information can help you.
If the reply helped you, please remember to mark it as an answer.
Best regards,
