DST update broken?

Post by bugger » Sun Mar 11, 2007 5:28 am

One computer has the last December update pack + all updates and the laptop has February update pack, and neither automatically adjusted for the DST changes this evening. The non-update pack computer downstairs automatically fixed the time. I tried rebooting. It is supposed to either 1) prompt at log in of time zone change or 2) automatically skip 2.a.m. at 1:59:59 for spring. Given that, I don't expect it to fall back automatically in the fall.

According to this: http://support.microsoft.com/kb/931836 the setting for CST (US & Canada) is correct. The internet sync didn't even recognize that (at the time of the sync) the time needed to be 4:20a.m. instead of 3:20a.m. I manually set it to 4:20a.m., then I set it to 5:20a.m. and did a sync and it went to 4:20a.m.

I too have a DST malfunction.

One of my computers had the OS installed prior to KB931836 being included in the update pack, so KB931836 was installed through windows update - it is fine.

This computer's OS was installed with the current update pack. It isn't changing to DST. If I run a time updater (Robomagic Socket Watch in my case), it will always set to 1 hour earlier than the correct time. This happens even with a fresh install.

If I open up date and time properties, uncheck "automatically adjust clock for daylight savings changes", click apply, then recheck "automatically adjust clock for daylight savings changes", all is OK.

FWIW, I use nLite, but as of this posting, no one has posted anything about this problem on the nLite forum.

RogueSpear - can you do a registry trace to see what if anything is changing when you uncheck and recheck that box?

Using Advanced Registry Tracer I disabled DST and came up with the following:

Code: Select all

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]
"ActiveTimeBias"=dword:0000012C
"DaylightBias"=dword:00000000
"DaylightName"="Eastern Standard Time"
"DaylightStart"=hex(03):00,00,0b,00,01,00,02,00,00,00,00,00,00,00,00,00
"DisableAutoDaylightTimeSet"=dword:00000001
Someone at work told me they had to do this manual step as outlined above as well. And with that install they had used Windows Update. Makes me wonder if this was re-issued or something.

elrico - Worth a shot anyway :). I'm at least encouraged (though saddened) that people are seeing it even when installing the fix manually. At least that means I'm in the clear of any wrongdoing :P

I tried integrating KB932590 and got the same results - doesn't work right until I toggle auto DST.

I already run a few autoit scripts at first boot anyway, so I just threw together another one to do the toggle for me until M$ sorts this out. Here's the code if anyone wants it:

Opt( "SendKeyDelay", 100 )
run ( "rundll32.exe shell32.dll,Control_RunDLL timedate.cpl" )
Sleep(500)
WinActivate("Date and Time Properties", "")
Sleep(500)
Send ( "{tab 9}" )
Send ( "{right}" )
Send ( "{tab 2}" )
Send ( "{space}" )
Send ( "{tab 3}" )
Send ( "{enter}" )
Send ( "{tab}" )
Send ( "{space}" )
Send ( "{tab}" )
Send ( "{enter}" )

*This works on a P4 @ 3250, may need to extend "SendKeyDelay" and "Sleep" for a slower computer
