I just received an email to remind me that the United States government made some changes to when Daylight Saving Time begins next year (Link to Californian State page but the principle is the same)
The stated reason is to reduce energy consumption.
However, I wonder if those implementing this change have any idea what a massive cost has been imposed on the world economy?
Just look at a list of the affected IBM software products.
The same search for Oracle (changes to dst 2007 site:oracle.com) yields nothing official-looking. Boy are their customers in for a shock!
And that's just some major software vendors (and Sun... ho ho). We can add in the impact on the countless independent software vendors and businesses around the world with home-grown software.
Add in the costs of missed meetings, VCRs recording the wrong shows and the effects on cell-phones and car radios and more and you quickly see quite how much work is involved in dealing with this change.
It's good to see that organisations are getting on top of this (well, some of them are...) But I think the true cost will prove to be far higher than anyone would have predicted when passing this change to the law.
[Usual disclaimer: I'm speaking for myself and not my employer. My opinions are my own. I have no idea whether my employer regards this change to DST positively or negatively]
