I highly recommend not bypassing this stuff and let your parents be parents. You're going to get caught and I'm sure it'll only get worse.
I used to have this internet time thing too, till they figured that it didn't affect me other than being on the computer longer.
You live under their roof which means you should follow their rules.
Get a job, move out, buy internet, and you can can stay up as late as you'd like on it!
