Passage of Time Solves PS3 Glitch
An anonymous reader writes "A quick update on the widespread PlayStation 3 glitch we discussed recently: as of last night (Monday, March 1st) the problem has resolved itself. I powered up my PS3 to find the clock was set to April 29th, 2020, but once I went into the system menu and set the date and time via the internet I got an accurate date. That seems to be the test of whether your PS3 is 'fixed' or not; Sony says you should be all set."
That this particular bug "fixes" itself in a relatively short span of time.
/dev/rtc, The standard hwclock command can be used to manage the RTC. Since the RTC is read only, the PS3 Linux platform support maintaines a value in system flash memory that represents the difference between the hardware RTC value and the Linux RTC value."
According to the documentation provided for PS3 linux, the clock that is embedded in the PS3 cannot actually be manipulated from under the hypervisor:
"Similar to a PC, a built-in real time clock (RTC) keeps the wall clock time for the PS3. The RTC is backed up by a battery and so ticks even if external power is removed. The RTC value can be read by a hypervisor call, but it can not be written. The RTC value monotonically increases and never rolls back. The PS3 Linux platform support uses the standard RTC userland interface
I'm assuming that this read-only clock "feature" is in some way related to DRM, to keep people from playing tricks with expiration dates. Worst case scenario, it is impossible to modify the RTC without hardware tinkering. Had this not been a transient bug, that would have meant massive physical recalls. More likely, it is possible for sony-blessed firmware updates to modify the clock. However, Sony can only push those either through the internet, or on physical disks. Since the bug was preventing PSN logins, the internet option wouldn't have been automatically available(though, since the issue is transient, it now is again). They would either have to mail out upgrade disks to affected users, bundle the upgrade with future game releases, or make their customers go to some support site and burn their own upgrade disks. Gigantic pain in the ass.
