Daylight Saving Time – 3 Weeks Earlier!

[inspic=29,left,,0]This Sunday, March 11 2007 at 1:59am begins Daylight Saving Time (DST)!
Unfortunately, this years arrival of DST may have mild affects on your computer. Unless certain updates are applied, the time zone settings for your computer’s clock may be incorrect during the new extended four weeks of DST.

Attention PC user:

  • New computers running Windows Vista are not affected.
  • All computers running the most recent version of Windows XP – Service Pack 2 (and have “Automatic Update” turned on) will have already received Microsoft’s ‘daylight-saving patch’ and are updated and protected.
  • Computers with “Automatic Update” turned off should download the patch from Microsoft.
  • Computers not running Windows XP – Service Pack 2 should make sure that the automatic DST is turned off in the control panel. The clock will have to be manually adjusted when needed.

Very Important!
If you’re using a desktop-based calendar program (ie: Microsoft Outlook) to store your appointments, you will need to download and install patches to correct appointment times. However, appointments entered before a patch is applied may still be off by an hour.
Microsoft advises heavy calendar users to download a small program called Time Zone Move that will adjust all previously booked appointments to the new daylight-saving rules.
Microsoft also suggests using caution with regards to scheduled meetings between March 11 and April 1!

Attention Mac users:

  • Computers running Mac OS X 10.4.5 (released February, 2006) are not affected.
  • Computers running Mac OS X 10.3, 10.4 should run Software Update to get the latest fix. Apple recommends that you should install the updates even if your computer is used in a time zone that is not affected.
  • Computers running Mac OS X 10.2.8 or earlier should turn off automatic DST and adjust your clock manually using Date & Time preferences.
  • Applications that run in Classic mode will abide by the Daylight Saving Time setting in Mac OS X.

If you’re not sure if your computer is updated, or just need assistance applying the latest DST patches, call or email me and I’ll be happy to help.
