    Cambia alla Ora estiva,Change to the daylight saving time,改夏令时了

     
    (SC)从3月25日开始意大利开始实行夏令时,把表拨快了1小时,与中国的时差从原来的7小时缩短为6小时(意大利标准时间为GMT+1,而中国是GMT+8)。记得我很小的时候北京也经常实行夏时制,但是已经暂停好久了。对于夏时制的有缺点如下:
    好处
    1、高纬度地区由于夏季太阳升起时间明显比冬季早,夏时制确实起到节省照明时间的作用。
    2、不少零售商对夏时制持肯定态度。美国的糖果商院集团已经游说美国国会将夏时制延长到11月,因为万圣节是糖果销售最旺的季节,而家长们不希望孩子们在天黑以后还在外面游逛。
    3、有人认为夏时制对患有夜盲症的人大有好处。
    弊端
    对低纬度地区,夏时制作用不大。尤其这些地方在夏天十分湿热,夜晚降临时闷热无法入眠,而清晨正是睡眠的好时间。
    其他争议
    夏令时让俄罗斯每年能够节约20亿千瓦/小时的电量,但这个数字只相当于两三个火力发电厂的发电量。该制度也使法国用于照明的能源消耗减少4%。有人认为夏时制在旅游业和能源消耗上获利不明显,还扰乱了儿童和老年人的生物钟,违反人的正常生理节奏。
