Daylight Savings Switch To Mess Up Electronics

The AP discusses how a change in the dates daylight saving starts and ends on, being instituted today to start in 2007, will affect applications on all computers and digital devices.

An energy bill President Bush is to sign Monday would start daylight time three weeks earlier and end it a week later as an energy-saving measure.

According to the article, daylight savings has remained unchanged since 1987, leaving computers and VCRs automatically compensating on the same date for a near-twenty-year period. Now, those dates don’t apply, but the electronics will have no idea.

Presumably, all future programs (like Windows Vista and future updates to MacOS) will have the new dates coded in, but previous versions of software will need a patch, and many companies are unlikely to provide one. Microsoft will almost certainly not patch Windows 98, Windows 2000 is unlikely and even Windows XP may be out in the cold two years down the line.

Meanwhile, if your PIM software (or handheld or phone) is more than a few years old, there’s a good chance it will use the old schedule. This means you will have to turn off the previously reliable “Adjust For Daylight Saving Time” option and change the clock twice a year an hour.

Needless to say, this will be quite annoying.

I hate daylight saving time. I have a theory that DST is becoming more irrelevant (and possibly uneconomic) as time goes by. Although people are using lights less do to the extra hour of daylight, they are using air conditioners more, do to the extra hour of heat. I think we all know the effect high-powered air conditioners have on the power grid, one far more so than increasingly lower-powered lighting. In fact, I believe it is more likely we would save money with an extra hour of nighttime than with more daylight.

That’s just my theory. I’m sure everyone’s got their own.

  1. […] Seventeen months ago I mentioned how the changes in Daylight Saving Time policy was going to wreak havoc with software all over the world, and I am being proven right. The new laws shift daylight savings to start three weeks earlier, starting with March 11 of this year (it would normally have started April 2, 2006) and ending two weeks later, on November 4 (instead of October 29).

  3. Get a life! Quite anoying, change the clock twicw in six months? Most of the PC clocks required adjustment for drift more often than tha.

  4. What PC clock needs adjustment anymore? This isn’t 1988 anymore. Windows automatically adjusts the clock for time changes. However, there are lots of automated systems that rely on a predictable calendar that hasn’t changed in many years, that is now being changed by the federal government based on questionably reasoning. There are lots of things that could go wrong. This isn’t about annoyance, but about the clocks not being as reliable as a system of time is supposed to be.

  5. There is NO solid evidence that, on the whole, daylight saving time saves energy.

    But oil is indeed involved: retailers and barbecue makers use it to grease Congress’s palms.

    Who cares about children who have to go to school in the dark. First things first. We want to spend our evenings shopping for crap we don’t need.
