An hour longer sleep summer time since today to end

Today, the clocks have been changed: from 3:00 to 2:00
Since Sunday morning the winter time is valid in Germany and many parts of Europe. At night, summer time has ended. At 3:00 am, the clock was reset to one hour at 2:00. "As expected, everything went smoothly that night," reports Dirk Piester from the Physikalisch-Technische Bundesanstalt (PTB) in Brunswick today the German Press Agency (dpa). Thus, the actually regular Central European Time (CET) has begun. Technically, the term "winter time" namely only a popular term for the time change.

The time change was introduced in the late 1970s, to save energy after the oil crisis in 1973 by a better use of daylight. But even by the forward and backward time can be found here, according to the Federal Environmental Agency no positive effect. Although citizens turn off their lights less often in the evenings in the summer, they also heat more in the morning and in the early hours of the morning - that is mutually exclusive, it said in 2007 in response to a request on the effects of the time change.

The physicists based in Braunschweig are responsible for sending a signal via a time transmitter in Mainflingen near Frankfurt so that station clocks, for example, jump back one hour. Although this is preprogrammed, the transmitter is then occupied overnight. Dirk Piester: "I also set myself an alarm clock at home to see if everything works."

In the winter months it is now an hour in the morning rather light and in the evening rather dark. The next time change is on March 27, 2016. Then the clock is again introduced by one hour. Nowadays, clocks have to be reset manually less and less often because this is mostly digitally programmed.

In the winter often in the fresh air
