Windows Mobile and extended Daylight Savings Time
Ryan Somma recently blogged about software glitches due to the extended Daylight Savings Time that was introduced by the US government’s Energy Policy Act of 2005. One of the issues that he experienced was:
My cell phone has been waking me up an hour early all week because it thinks that Daylight Savings Time (DST) began last weekend. I can’t change the time because it’s managed by Cingular, so it’s the fault of their systems.
My cell phone’s been wrong this week, as well. I know I applied a DST patch back in the spring, but I think I must have installed a new copy of Windows Mobile on my phone since then, and it didn’t include the patch.
At first, I tried setting my phone’s clock manually, but then I experienced the same automatic time setting that Ryan did, care of Cingular. Yesterday, I finally got tired of seeing the wrong time, so I changed my time zone to Atlantic (GMT-4), and then went looking for the Windows Mobile Extended DST patch.
You can find the necessary patch(es) and instructions for Windows Mobile devices here, if you still need them. My phone is back to the Eastern (GMT-5) time zone, now, and is showing the correct time. Hopefully it will adjust properly on Sunday, too.
On a humorous but not directly related to DST note, I accidentally set my alarm clock one hour ahead when attempting to turn it off, earlier this week. Later that day, I was sitting in my room, working on my laptop, and tried to see what time it was. My laptop said one thing (the correct time), and Lacey’s alarm clock showed a similar (+/- 5 minutes) time, but my alarm clock was an hour ahead, and my cell phone was an hour behind. That was rather confusing. :)

There’s always WhatTimeIsIt.com … it’s slightly more useful than http://www.IsItChristmas.com :)

Great post. It’s nice to know we’re all in this confusion together. Thanks for the link. : )
