From the IT person for my department:
Congress changed Daylight Savings Time from the first Sunday of April (1st) to the second Sunday in March (11th). This is new, many computers, Palm Pilots, Blackberries, cell phones and
software may not yet be equipped to handle this change. We are beginning to run into trouble with scheduling events in the Outlook calendar between March 11th and April 1st. Depending on which computer you use to look at the event you may see the event occur an
hour earlier than you had intended. If you notice that any of your devices display a meeting at the incorrect time let me know. I will work with you and my colleagues in Wharton Computing to fix things so the correct time is displayed.
I would recommend that for any appointment you put into an electronic calendar for this time that you include the time of the appointment in the subject of the appointment. Rather than scheduling a meeting titled “Meeting with Lowell” you should schedule a meeting titled “12 noon meeting with Lowell.” You may also want to keep a close eye on your home video recording devices, Airplane / train tickets, Concert tickets, etc. to avoid any surprises.
Quite an interesting unintended consequence of the daylight-savings change (which, as I understand it, was done to save on energy usage). It shows just how brittle some aspects of our life can become as we rely increasingly on machines. [Werblog]
