had problems playing installed offline games (which queried the system timer as part of startup) and using system themes. At the same time, many users noted that the console's clock had gone back to December 31, 1999. The event was nicknamed the ApocalyPS3, a play on the word apocalypse and PS3, the abbreviation for the PlayStation 3 console. The error code displayed was typically 8001050F and affected users were unable to sign in, play games, use dynamic themes, and view/sync trophies. The problem only resided within the first- through third-generation original PS3 units while the newer "Slim" models were unaffected because of different internal hardware for the clock. Sony confirmed that there was an error and stated that it was narrowing down the issue and were continuing to work to restore service. By March 2 (UTC), 2010, owners of original PS3 models could connect to PSN successfully and the clock no longer showed December 31, 1999. Sony stated that the affected models incorrectly identified 2010 as a leap year, because of a bug in the BCD method of storing the date. However, for some users, the hardware's operating system clock (mainly updated from the internet and not associated with the internal clock) needed to be updated manually or by re-syncing it via the internet. On June 29, 2010, Sony released PS3 system software update 3.40, which improved the functionality of the internal clock to properly account for leap years. Features PlayStation Portable connectivity PlayStation Portable can connect with PlayStation 3 in many ways, including in-game connectivity. For example, Formula One Championship Edition, a racing game, was shown at E3 2006 using a PSP as a real-time rear-view mirror.

It is also possible to use the Remote Play feature to play these and some PlayStation Network games, remotely on PSP over a network or internet connection. Sony has also demonstrated PSP playing back video content from PlayStation 3 hard disk across an ad hoc wireless network. This feature is referred to as Remote Play located under the browser icon on both PlayStation 3 and PlayStation Portable. Remote play has since expanded to allow remote access to PS3 via PSP from any wireless access point in the world. PlayStation Network PlayStation Network is the unified online
