I have an application that looks at the system time and records the datetime. We give out demos and license by time.
One customer claims to have blocked my application from seeing the time so it always runs. He wouldn't say how but just said he would "not let it look at the time." Before I dig into this has anyone heard of this or know how to do it? He's not really a hacker but is tech savy enough to find things other people have done.
