So what you do, is you set your clock to the minute before your spread so, for example, your target time was 13:15:14, you'd set your clock at 13:14:00 and the instant the clock turns to 13:15:00, reset, and with your calibration, you know it should take you 14 seconds to get from that point to starting your game, so you should be able to hit continue at 13:15:14. =D
