Using the date to allow users to have a grace period

Hi all,
I have an app that users can add plug in modules to, each module gets a key supplied by us to activate the module for permanent use, the modules however must work for a trial period, say 30 days, to allow the user a chance to test that the module is what they want before paying for it.
The problem is, when the module is installed the app records the date it was first found and uses that date to give the grace period i.e. for 30 days a message is given stating how long they have left before this module stops functioning. Obviousley the user could change the date on their PC after the 30 days to be within the 30 day trial period, is there any way I can record the actual date so that if the user does change the date the module still knows how many days it has been used for.
Or is there a better way to allow a grace period?
Many thanks
Joe .
