Clocks in much of the United States ticked ahead one hour last weekend for the new Daylight Saving Time adjustment, which we explored in "Daylight Saving Time May Bite the Out-of-Date" (2007-01-29) and "Daylight Saving Time Saved" (2007-02-19). If some of your devices weren't updated for the change on 11-Mar-07, here are some quick resources to get you back on track.
Mac Updates -- For Macs to deal with the change automatically, make sure to install either Daylight Saving Time Update (Tiger) (for Mac OS X 10.4.8; Mac OS X 10.4.5 and later had some, but not all, updated DST info) or Daylight Saving Time Update (Panther) (for Mac OS X 10.3.9), which are available via Software Update and as separate downloads. If you're still using Mac OS X 10.2 Jaguar, look to a modified patch at AFP548.com. Apple also released updates for Java: Java for Mac OS X 10.4, Release 5 and Java for Mac OS X 10.3 Update 5.

Other Devices -- I own a Treo 650, and in the days leading up to the switchover I was bombarded with email, voicemail, and text messages urging me to upgrade my device. I'm guessing the cellular phone companies did everything they could to alert their customers to avoid a tech-support nightmare.
Patches for some recent Palm OS handhelds and Palm-branded Windows Mobile smartphones are available at Palm's Web site.
If you use a Blackberry device, Research in Motion (RIM) has posted a patch to download and install.
Do you rely on a TiVo to record your favorite television programs? This page at tivo.com discusses how the time change will affect customers, particularly those who have set up manual recording times on some devices.
Lastly, if you're using an iPhone, well, "time" has no meaning while you work at Apple getting ready for that June launch. Don't worry, someone will deal with the DST adjustment and will be bringing emergency food and caffeine soon.
