desktop-application

I am creating a desktop application using AIR. In that application user is allowed to download some resources which have life span of 2 days. I am storing the date when the user is downloaded.

But how can i check whether the date is passed 2 days or not? Right now I am checking with the current system date.But when the user changes the system date to back, it will start to work which i dont want.

How the desktop applications say like flex builder and all having trial period.? How are they tracking the dates remaining?
