Sony says a glitch that caused a global gaming lockdown for PlayStation 3 owners is due to a bug in the clock functionality of older PS3s. The lockdown affects owners of older PS3s as well as those who try to play newer games, which use trophies, such as “Heavy Rain” and “Final Fantasy XIII.” It also prevents users from connecting to Sony’s PlayStation Network. At press time, Sony was still working on the problem. The glitch struck Sunday when users powered on their PS3s, whether or not the devices were connected to the Internet.
