IMPACT OF THE TIME CHANGE

Every year, companies send out all-hands memos to employees asking them to help identify systems that might be impacted by the time change.  These systems range from automated wake-up systems in hotels to systems that schedule airline crew members and slot aircraft for gates.  In addition, many computer-to-computer systems may also be impacted.

With the exception of the calendaring problem mentioned earlier, most business travelers should be covered by now, at least insofar as their desktop or laptop computers are concerned.  Microsoft released a single global time zone update for Windows XP Service Pack 2 and Windows Server 2003 (and for Windows Server 2003 Service Pack 1) that automatically installed.  This update included updates for all DST-related changes from 2007 or that have taken place since the operating system’s original release.  The updated time zone definitions ship with Windows 7 and Windows Vista.

That covers operating systems but doesn’t mean that we are out of the woods yet.  Most current programs with calendar support should have been updated by now but if yours has not, any meetings that fall within the extended Daylight Saving Time period before the application of extended DST rules will appear incorrectly after the extended DST rules have been applied, namely they will appear an hour later than originally scheduled.

WHAT YOU CAN DO TO AVOID PROBLEMS

First, double check any calendar entries or plans for the coming two week, i.e. March 11 through March 25.

Second, make certain to adjust or update your operating system to apply the changed Daylight Saving Times rules if this hasn’t already taken place. It pays to double check.

Third, remember that Daylight Saving Time is not observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, and Arizona (with the exception of the Navajo Nation). Until 2006, the counties in the Eastern Time Zone of Indiana did not observe Daylight Saving Time and remained on standard time year round. As of April 2006, all of Indiana observes Daylight Saving Time.

Finally, after changing all of your timepieces, remember to get a good night’s sleep.
