I booted over to ydl today and the time changed, I thought nothing of it. I just changed it back with the time servers. After about 5 hours I wanted to play some fallout 3 so I booted back to game os, and immediately ran into psn sign in problems, and my heavy rain dynamic theme was gone. So then I remembered a sticky in billbs guide: How to: Fix network failure after booting to game OS. I went through that whole thing. And my problem still wasn't fixed.
So I turned to google. Turns out all generation 1-3 "phat" ps3's have had some sort of hardware clock failure, or malfunction.
This is the best info I have seen here
http://neogaf.net/forum/showthread.php?t=388872Everyone READ THIS PLEASE.
Here's what's going on right now: something with the PS3's internal clock has borked in some pre-slim models. This is not a PSN issue; it has to do with your PS3's clock. This clock is NOT related to the OS clock. It seems to be a leap year bug. Setting your clock ahead will do nothing. All PS3s around the world were affected at the exact same time.
Does this affect me?
-If you have a Slim PS3, you're good to go. Continue playing it as normal.
-If you have a "fat" PS3, you may be affected. Some fat PS3s have worked ok, but it seems a good majority have been bugged.
What does this bug mean?
-If affected, your date and time has been set to a random past date. This prevents you from signing into PSN, playing any PSN games, or using any DLC. Your trophies will also not display correctly or be able to sync.
How do I fix it?
-You can't. Even if you don't sign into PSN, it won't help. This is a hardware issue.
So, what do I do?
-Wait 24 hours. Other products that have had similar bugs have corrected themselves after the "bugged" day. On Monday around 6pm central time, all PS3s will automatically correct themselves...maybe.
-If that doesn't work, we'll need a firmware update from Sony, which should be a pretty important priority for them right now.
Did I lose my data/themes/etc?
Your save data/games/dlc/themes are fine. They'll be fixed when the PS3 is fixed. Trophies are uncertain right now, but they'll be fine if you've synced them before the PS3 was bugged. Unsynced trophies are an unknown right now.
If I have a bugged PS3, can I still use it?
It's probably not a good idea, as I have no idea what will happen to the trophies you earn during the bugged time. Movies/media will work fine.
So there ya go, my handy FAQ.
Sony's twitter
We're aware that many of you are having problems connecting to PSN, and yes, we're looking into it. Stay tuned for updates.
PSN status update: We're narrowing down the issue and continue to work to restore service to all. Updates as soon as we have them.
PSN status update (part 2): Readers/followers are confirming that "slim" units (120/250 GB models) are connecting normally.
Whats weird is the themes are affected, I have about 4 or 5 dynamic themes and they all show up as "Corrupted Data" and about 5 more that are not dynamic show corrupted as well.
