Simple DST Fix – How Come Nobody Has Mentioned This?

Sometimes we make things so complicated and then we read a simple fix. I was over at LG this afternoon and read a post by The Shadow which stated for home users:

  • Just double click the little clock in your system tray.
  • Then, click the “Time Zone” tab and at the bottom of the window UN-Check the box that says “Automatically Adjust
  • Clock for Daylight Savings Changes.”
  • OK the window to close it.
  • When the time comes just manually reset your system clock and all should be OK.

It made me kind of laugh. For the past several weeks there have been many posts about how DST could be worse than the Y2K problem, which overall was a non-event. And now here is posted something that is so simple it made me wonder why no one had posted this before.

But I guess doing something the easy way wouldn’t make for interesting headlines. :-)

Thanks, Wayne – two thumbs up!

    I think the main problem will be with all calendars out there that need the correct DST information to coordinate meeting invitations across time zones. With all the PDAs, smartphones and blackberries managing the pod-people out there, there are going to be some missed meetings when all of the devices are not corrctly updated and they try to sync them.

    Agree. I already patched Outlook on my systems.
    Thanks for your comments.

    That doesn’t help the fact that you still have an operating system with incorrect timezone definitions.

    Translations to/from UTC time will be skewed because you’re technically saying “I am always GMT-5″ when you uncheck that ‘automatically adjust for daylight saving time’ box. Then the second part of this fix is changing the system time which is saying “GMT is really an hour later now”. In reality we need to shift EST to GMT-4 for the duration of Daylight Saving Time.

    This probably isn’t the place to discuss the problem with the OS only keeping one set of DST rules for each timezone but if you update your definitions to the new rules and go looking at historical data from (ex:)3/24/06 then you’ll get an incorrect time if you’re letting windows do your translation to local time.

    Hi Nick,
    Thanks for your observations.

    The above fix mentioned by Wyane above wasn’t posted by anyone else because it won’t work. Not only do you need to adjust the time up front, but your computer needs to know that the duration of the time change has also changed. Wayne’s fix above won’t make that correction, so it will revert back from daylight saving on the wrong date unless you use the patch to tell it the new change back day and time.

    Hi Mike,
    Thanks for the information. So it would seem using the patch is the best way to proceed.
