i dont understand,why only europe change the time,and other continents not!
in the beginning of the time change the plan was,that we all should save engergy ,and light,when the people go earlier to bed,when its dark out side,but exactly the diffrence happen!
here the weather is crazy,last week we have very cold,minus 10 in the morning and maybe 7 on day time!
currencly we have foehn,and very hot on day time,over 15 degrees,until next 5 days,blue sky no rain,but very cold air!
