Can you have scheduling start your rest time from when you actually left the airport? They should be able to do that for you. If not, call the chief pilot to get them to help. If they dont want to help, tell them you're calling in 'fatigued' and will be contacting the FAA to discuss the safety policies of an airline that intimidates its crews into being cheated out of much-needed rest. Then again, maybe you're on probation
