Owners of the older generation PlayStation 3 game systems are being warned by Sony not to play online until a coding error in the clock functionality of the system, similar to the Y2K bug, is fixed. Errors began being reported recently that resulted in the system date being reset to Jan. 1, 2000. Using the systems online could cause errors, make it impossible to record gaming achievements or restoring some data, cause an error message saying the user has been logged out of the online game network, and result in game trophies to disappear. The error does not occur in the newer slim version of the PlayStation 3 that began shipping in September '09.
