From the article: In 2005, Reps. Edward J. Markey of Massachusetts and Fred Upton of Michigan drafted legislation that would extend daylight-saving time nationwide. Congress approved the amendment, which called for clocks to be sprung forward three weeks earlier in the spring and one week later in the fall. The change went into effect last year. Dear legislators, if you're going to fiddle with the representation of time, please could you do it with a minimum of three years notice. This would save a vast effort in retro-fitting critical system upon which all of society depends. Providing sufficient notice would be vastly more cost effective and therefore more productive for everyone.
