Hi All,

My clock (time) in my MacBook always goes one hour back My clock in MacBook goes forward always and I have to manually set it to the right time after boot. This happens even for the Bootcamp partition running Vista. I am not sure how we change the MacBook's time in EFI (as we do in BIOS).

Can anyone help me out here? I have also tried syncing with the Internet Time Server (asia.apple.com) but still the time goes one hour back and DST for NZ is only on April 6th Embarassed

Chaks

freitasm:

Have you checked that you have the correct timezone setting? Have you checked that Apple has issued any updates for timezones?



I'm sure I saw a timezone update a few months back (before daylight savings started).  Try going to http://www.apple.com/downloads/macosx/apple/ and see what you can find.

Also, what version of OS X are you running, and are you up to date with your patches?

be aware, Windows prefers to set hardware clock to local timezone. only a problem when dual-booting, etc. sensible OS and sensible admin will set hardware clock to UTC.

Chaks what Macbook do you have? It must be a settings issue. I had the 2.20GHz and now have the 2.4GHz and I have no such issue.

I sync with time.apple.asia.com (thats the default, I have not changed it) and my timezone is NZDT Wellington.

I have just done all default software updates - no manual trickery here.
Do you have any crazy PIM apps or other things that might stuff the TZ around?

First, my apologies friends, the time is not going one hour back, but.... my current time in my Mac is Wednesday 26th 1.44 AM Embarassed

barf: be aware, Windows prefers to set hardware clock to local timezone. only a problem when dual-booting, etc. sensible OS and sensible admin will set hardware clock to UTC.

I seriously doubt that because this whole issue has started after installing Vista in my Bootcamp Partition. But then, even in Vista, I have the option to set from Internet Time...

Here are my screenshots,

I am really stuck here and not sure what to do Embarassed

It was:

12:41 PM on 25th March 2008 at the ACTUAL time of the screenshot

but your screenshot shows:

1:41AM on 26th March 2008?

That's a difference of +13 Hours!


I've seen somewhere (about Hackintoshes though :() about time issues between Windows and Macs, and solutions...

Sorry if you've already realised it, I looked at your post quickly before I knew that you would have already known that.

Here is a link - hope it helps! (deliberately not linked)

As has been mentioned, Windows stores the local time to the hardware clock, whereas most other OSs store UTC to the hardware clock. As the difference is 13 hours, this says that when you boot to Windows, it updates the time, and on shutdown it writes the localtime to the hardware clock. When you book back into OS X, it reads the harware clock, adds 13 hours (NZDT) and gives you what you see. When it syncs with the Time Server (which happens later than in Windows which seems to do it just after booting) it will set back to the correct time.

Annoying, I know - I had to deal with it when dual booting too!

As few have told in this thread, it is Vista which is creating problems and playing with the Time ( Yell ). I changed my time in Leopard & also chose to automatically set time and booted into Leopard nearly three times and the time is good now. But I havent booted into Windows (Vista) yet, but had made a small registry change. Have to see whether it works. There are few methods suggested from @manhinli's link which I have to try if that doesn't work.

@tonyhughes, is your Macbook good with XP Laughing. The strangest part is that I hadn't changed the time in Windows at all and I think because its set to synchronize with Internet Server, this might have caused it. (D'oh)
