Countdown Timer Bypass

I am looking for someone to write a script or by what ever mean necessary bypass countdown timers on websites like [login to view URL], [login to view URL], [login to view URL] [login to view URL] and also bypass an spa page from finishline.com. Timers on these website are used to release footwear at specific times. Once the timer reaches zero, the footwear is available for purchase. Rather than sit and wait for the timer to reach zero along with their sites bogging down and crashing due to high traffic at the time of release, I would like to bypass these timers.
