^ All parts of Arizona (except the Navajo Nation community) observe Mountain Standard Time all year round, and MST = EST – 2:00. However, on March 10th this year, DST starts in EST regions and the clocks shift ahead an hour, meaning at that time MST = EST – 3:00. Therefore (if I am correct) you'll be running Sonic Riders at 3:00 PM your time on the Tuesday. (Even if you do live in the Navajo Nation community it only enters DST in April so it'll be no different there.)
