_NY Times_ [and me]: Two years ago, when Congress passed a [stupid, pointless] law to extend daylight saving time by a month [despite contradictory studies about whether such moves actually have a measurable positive effect on energy consumption], the move seemed a harmless step that would let the nation burn a little less fossil fuel and enjoy a bit more sunshine. [But, of course, they didn’t think of the *millions* of computer systems that would need to be updated to reflect the change.] […] For the roughly 7,000 public companies in the United States, Mr. Hammond estimates the total cost of making computer fixes to deal with the daylight saving time shift at more than $350 million. “It’s causing a lot of corporate technology people sleepless nights,” he said.
