Indiana will observe DST across the state: pity the confused servers

Indiana, a state that straddles two timezones and only spottily embraces Daylight Savings Time, is planning to observe DST on a statewide basis starting April 2. The problem is that PCs don't know about this, which is gonna screw up all kinds of systems, putting them an hour out of synch:

"This is like Y2K except this one is really happening," said university IT spokesman Steve Tally.

Currently, most Indiana computer users set their PCs to a special "Indiana East" setting -- Eastern time that doesn't spring forward every April. Starting this April, however, they'll change their PCs to Eastern Daylight Time. The few who observe Central time set their computers to Central, and will also make the switch. Tally predicts the changeover will create havoc with the widely used Microsoft Outlook calendar application. When the time changes, he said, appointments will still be listed according to the old Indiana East time. The calendars of Central time Outlook users, in turn, will continue to list appointments according to Central time.

Update: Mark sez, "I happen to be an IT manager for a philharmonic orchestra in Indiana and the changeover is going to cause massive problems for anyone who uses outlook as a calendar. By the time this is all said and done, it's going to end up costing businesses in this state a lot of time and money. Perhaps the greatest irony is the fact that our governor pushed the change under the premise that it was going to increase revenue in the state. I've been actively encouraging fellow IT professionals in my area to contact the governor and give him an idea just how much the change is costing their company in money and man hours."
