There's something I don't understand here: According to the CNN
article, US may expand daylight-saving period by two months, from first Sunday of March to last Sunday of November, which leave only three months of year in the original
time. The changed is justified by saving 10'000 barrels of oil a day, which is less than 0.05% of the daily oil consumption in US.
But my question is: If daylight-saving in March and November is so good and saves energy, why not save more and drop the hassle totally: Just adjust the time one hour and save all year round? It's just asking people to go to work at 8 instead of 9, but in a way they don't nag.
