The day light saving system causes lots of chaos in North America. 1, It disturbs the sleep cycle of everyone. 2, it increase the confusion of the time of flights, trains and other very important appointments twice a year. 3, It increase the production and maintenance costs to computer and smart phone operating systems and any automatic time adjustment systems in our life. 4. The benefits and energy saving by day light saving is hard to prove as most offices and factories DO NOT use sunlight for illuminance at all, and even people use natural light may adjust their habit accordingly. So the day light system has lots of problems but hard proven or iota of benefits and it is against our natural. We strongly suggest the US and Canada government to abolish this stupid system ASAP.
