A disastrous bug that took a swath of older-model "fat" PlayStation 3 consoles out of commission all day yesterday has been resolved, Sony says. PS3 users -- not including those who own PS3 Slim consoles -- found themselves unable yesterday to connect to the PlayStation network or play any offline games that required Trophy synchronization, such as recently-launched Heavy Rain. The company now knows the issue was caused by a mistake in the PS3's clock. "We are aware that the internal clock functionality in the PS3 units other than the slim model, recognized the year 2010 as a leap year," says senior communications director Patrick Seybold on the official PlayStation blog. "Having the internal clock date change from February 29 to March 1 (both GMT), we have verified that the symptoms are now resolved and that users are able to use their PS3 normally," he adds. Users who continue to see incorrect times displayed on their consoles can manually change it, Sony says, promising to keep users updated if any further information is needed. "We apologize for any inconvenience this may have caused," Seybold concludes.
