Have you considered why the "auto logoff" feature is really there?

Having understood that, what if you forget to turn off your magic program when you finally leave the building? If it's there for your security, then someone else will have free access to your account in a public building.

Also consider that what you're trying to do could be considered by some harsh regimes as computer misuse (writing a program to circumvent a policy decision of the management). Getting bumped off your course is not what you want.
