Description Andrew Cagney 2005-05-03 14:16:52 UTC
Given "System clock uses UTC" disabled. It would appear that Apple keeps the hwclock in local standard time. even during summer. The system clock being adjusted by an hr during summer. GNU/Linux, on the other hand, appears to think that the hwclock should always exactly match local time. During summer this puts GNU/Linux and Apple one hr out.
Comment 1 David Woodhouse 2005-05-03 14:33:42 UTC
Apple stores the UTC delta in XPRAM, and I believe the kernel's RTC driver automatically compensates for it -- thus you should be telling userspace that the system clock _does_ use UTC. Can you show the output of 'dmesg | grep GMT'?
Comment 2 Andrew Cagney 2005-05-06 01:23:49 UTC
Many reboots later (this really scrambles the clock): System clock uses UTC disabled: Apple==21:xx; Linux=20:xx System clock uses UTC enabled: Apple=21:xxx; linux=16:xx GMT Delta read from XPRAM: -300 minutes, DST: off
Comment 3 Nils Philippsen 2006-03-14 15:45:15 UTC
Guys, I really don't think this is a s-c-date problem, can you please change it to something more appropriate (don't ask me what is more appropriate -- I would have changed it by myself if I knew).
Comment 4 Nils Philippsen 2006-04-07 10:05:37 UTC
I can't fix this in system-config-date, I think this can only be fixed in util-linux (hwclock) or the kernel. Pick which one you like best ;-).
