Testing by changing date and time

We are using IsGenuineEx and we want to check the behavior of our application when we deactivate the serial from the web site. It seems we have to wait at min daysbetweencheck and at max daysbetweencheck+graceperiod for TurboActivate to connect to the server. If we advance the clock of daysbetweencheck+graceperiod to force connection it seems TurboActivate detects this and invalidate the registration, because even if we do not deactivate on the web site, we get a deactivated status. Is it the expected behavior? Is it normal that we have to reactivate?Is there a way to test our code by simulating the period has elapsed without TurboActivate anti tempering check detecting it?

Yes, TurboActivate detects many forms of date/time fraud (and gets more detection methods with each new version).

Is there a way to test our code by simulating the period has elapsed without TurboActivate anti tempering check detecting it?

No, not really. Just set "debug values" for the IsGenuineEx call. Like 0 days between checks and 0 days of grace period.
