NIST-F1 Cesium Fountain Atomic Clock
All is not well with the daylight savings time change...

So as we all know daylight savings time hit us early this year thanks to Congress trying to save energy. For those of us who follow the DST practice, if you're reading this and you haven’t set your clock forward yet you’re an hour late.

My computer and the computers I maintain didn’t handle the switch well at all. In fact I’ve had to go around to each of them and set the clocks by hand. Only there is a glaring problem with this strategy -- I also have my computer clocks update to the national atomic clocks using AnalogX’s Atomic TimeSync so when I made the change, 120 seconds later the clocks were off by an hour.

To say the least in a small operation this is a gross annoyance but I can imagine that in a large IT Infrastructure it can be a downright painful. I should mention there is a fix by setting a Time Offset in Atomic TimeSync by 1 hour the problem is solved at least until we change our clocks back.

To make matters worse the tools and websites Microsoft has thrown up to help users with the change don’t work. The tools throw non-descript error messages on the machines I try to install them on. I also must validate each of the workstations for genuine advantage before I can download the software that doesn’t work on the computer ... so because I have set up my clients computers to keep the correct time at all costs and the software to fix the “problem” won’t work I’ve got a load of computers that are now an hour off.

On a side note, wouldn't you be better off contacting the makers of AnalogX’s Atomic TimeSync and asking them for an update to the program, since it is the software setting the time on your computers? That is what I would do at least...

My atomic watch updated fine. I am not sure if that is because it is compliant (even though it is over 3 years old) or if the Atomic clock in Denver that it gets the signal from also sends out a day light savings time signal.

Any way you look at it though, your problem doesn't sound fun. I thought that network computers were all suppose to get their time from a local server which was set to a government atomic clock? Then if you had problems you would only have to change the time on one computer and the rest in the network would pick up the change.

I'm half-certain most internet time servers just report the digital value in seconds, or milliseconds, or even higher resolutions, since 1970 in GMT or UTF format, without specific timezone information, and it's up to the client to apply the timezone offset -- thus this problem.

There are alternative protocols that provide the timezone information, and other features, but I don't know that much about them.

Radio-based atomic clocks operate differently... not sure how they work either.

eg, local network servers would have the problem too, you'd have to set everyone's timezone on every client...

True, but you could just change the time on the server, and not worry about the DST settings on the computers. One change at one location.

I still think an AnalogX’s Atomic TimeSync patch could be made that adjusts the time it sets the computer to by 1hr. They might not want to do the work though, especial since it is less then 2 weeks till normal day light savings time goes into effect.

I highly suggest you sign up for Microsofts "TechNet" newsletter as they sometimes contain very useful info. The following is what the latest "TechNet" issue had to say about DST:

The United States Energy Policy Act of 2005 went into effect on 11 March. Hopefully you all passed that date with no issues, however I wanted to draw your attention to the Daylight Saving Time Help and Support Center. There you can find a rundown of all products affected by DST. You can also participate in webcasts and technical chats geared to help you apply the updates. Also check out Microsoft IT Deployment Guidance to learn about the Microsoft internal best practices on easing the DST transition.

Thanks for the heads up Chillin, I was on the technet mailing list some time back and mysteriously stopped receiving them and forgot to resubscribe. Thanks for the links as well they were very helpful, I just wish Microsoft had paid as much attention to the consumer notices they sent out because the tools linked in those message did not work, at least for me.
