The clock on my PS3 has been way off for a long time now... I'm not sure if that's because it was unplugged too long at one point, or because it keeps bad time... I've just never bothered to correct it.
Is your clock fast? Every PS3 I've seen has a fast clock. After only a month or two mine will be ahead by 2 or 3 minutes. I like how you can set the time via the internet, but it would useful if they would add an option to have it sync on it's own periodically.
I don't mean to impugn your programming abilities, but you're completely wrong about that. The zoneinfo file has been the method to solve this for a very, very long time.As a programmer, dealing with time, time zones, etc is one of the things I dread. If I were working on the OS for an entertainment device that is used in dozens of countries with different DST/summer time start and stop times, I'd probably say screw it, let them change their own damn clock.
Go to settings, then Date and Time settings. You can manually adjust it or set it by the internet.
the internet option didn't work for me today.
also there is a DST option for standard and Daylight Savings. Not sure what the difference is though.
