clock reset

When I switched on my mac today the clock had reset itself. Everything else seemed ok - although the wireless password has disappeared too.

Should I be concerned about this? / what's the problem?

Thanks

Macbook, Mac OS X (10.5.6)

Hi,

This happend also to me today. Even with full battery. This was what I did:

http://support.apple.com/kb/TS2538?viewlocale=en_US

It never reseted since then (that is in fact in the few hours after it, even with restarts).
It is also possible that something is wrong with the built-in firewall. Because at same time of the clock reset, I had to allow three kernel processes to receive information form the internet (two I still know: KRB5KDC and nmblookup). These processes you also need to "see" the airport extreme/express machines and any printer plugged on it.

I have been having trouble with my Mac book, every time it restarts after a shut down
the Calendar will reset to 1 JAN 01 and the wifi setting will have reset.

I was unable to find a contact number for Apple to help me with this, the only number
I found was (U.K. iPhone, iPod and Mac technical support: 0844 209 0611)
but it only give the option for Iphone support and they could not help.
Why do Iphone have 7 day call support but my Mac which cost me several times
more does not.

Very similar issue....Put my MBP to sleep, opened it the next day and it wouldn't wake (not uncommon) so I had to hold my power button down to restart. When I restarted it asked me which partition I wanted to boot to; Mac or Windows (Not supposed to do this, settings set to automatically start to OSX). When I logged in my clock was reset to Jan 1 2000 and the completely wrong time. In the middle of writing this post it has corrected. In addition my Airport password was no longer stored, my Safari passwords are not saved. User names are still there and appear under the Preferences of Safari. My battery did not die, it is at 75%. I keep being asked to reauthorize security certificates. Any clues??? May have other issues that I haven't discovered yet.

This has just happened to me as well.

I left the MacBook on overnight by accident, it drained the battery... when I started it up today, the date was set to January 1, 2001, and my wireless network details were erased.

I only bought my MacBook two weeks ago, so this worries me a little!

Has anyone reported this to Apple and been advised what the issue is? If it's just a problem with Leopard 10.5.8, then that's fine, but if it's some kind of hardware problem (not retaining clock data etc when the battery is flat) that would be bad news!!

Love to hear others' thoughts on this...

Cheers

The same thing happened to me today. My battery charge was around 50% or more and when I booted up my computer my clock information had been incorrect, and I had been asked for my wireless password. I had just shut down my computer less than an hour before.

After this occurred, I shut down my computer and turned it back on to find that time was correct, but it still asked me for my wireless password. After typing in my wireless password, I then proceeded to restart my computer yet again, and this time it started up normally, with no problems regarding both my wireless password or my clock.

Does anybody know why this happened and how I can fix the situation so that it does not happen again?

Thank you!

Hi,


The same thing happened with my MacBook: wonky time & forgot AirPort.

I called AppleCare and walked through resetting the SMC, which solved the issue.

Here is a link to resetting the SMC:

http://support.apple.com/kb/HT1411?viewlocale=en_US

And one for removing and replacing the battery (which I found a bit confusing until I looked at this article).

http://support.apple.com/kb/ht3053

When I restarted, the time was back to normal and AirPort hooked up. However, my CPU was almost 100% used by iCal Helper and then I got Alarms for all the events from that wonky date.

After closing all the Alarms, I restarted and the computer seems to be fine now.

I hope this helps others.

hi,
this just happened to me today as well.

after work i shut down my MBP, took it home, powered it up and the clock reset itself to 12/31/2000, i got an error that the computer's date was set to before Jan 1, 2008 and some applications would not respond correctly, and i got some firewall notifications from programs like "configd" and "mdnsresponder" to allow incoming traffic. and my wireless password was gone. the battery was not drained.

i manually reset the clock and am running anti-virus now (just to be safe), and i'm glad i found this thread....not sure what's caused it but i'll report back on anything i find. so far it seems to have reconnected to my wireless on it's own.

Well, it happened to me, also. I had just restarted my mbp13 (after having to force quit Firefox, which had frozen during a download). The system came back up with a warning that the clock had been reset/initialized/hosed, and my airport wasn't recognized. Without net access, the clock couldn't be reset using the time server. I turned the mbp Airport off then back on, and had to supply the base station password. I got the network back, but Keychain still refuses to allow viewing passwords, despite the fact that I verified the codesig (codesign -vvv /Applications/Utilities/Keychain\ Access.app). (I'm not sure if I had attempted to view passwords subsequent to upgrading to 10.6 several weeks ago.) Aarrgh.
