Here is some information supporting Macs through the switch to Daylight Savings Time (on its new date of March 11).

For some software and versions of OS X, software patches are available that correct the time zone and DST rules so that that your system clock and applications which depend on time/data date adjust to the change on their own. In other cases you may need to adjust the system time and application time settings yourself. Below are some guidelines for assisting your Mac users with the change.

	For OS X

• Version 10.2 (Jaguar) or earlier - You will need to reset the clock by hand on March 11 and then again on April 1.
• Version 10.3 (Panther) and 10.4 (Tiger) - Apple has released a software patch that will allow your Mac to make the switch at the appropriate time this year. To install the patch, run Software Update from the Apple menu in the top-left corner of your screen, and choose to apply all new available updates. A reboot is required at the end of the process.

	For Microsoft Entourage

• Entourage X - Users running this version should upgrade to Entourage 2004 as soon as possible.
• Entourage 2004 - Download and install the Microsoft Office 2004 11.3.3 update.

For all other applications, the website at http://www.dstpatch.com/ may be useful in tracking down additional applications you support and which may be affected by the new DST switchover date.
