Clocks will be set one hour back in the early morning hours of Sunday, October 27th 2013. Exactly at 4 a.m. clocks will have to show 3 a.m. The action is due due to daylight saving time, a process that may confuse our biological clock for a week or so and cause a big surprise to milk cows, but it helps us save energy.
Next change of clocks to summer daylight saving time will be on March 30th 2014.
PS I usually do not bother to change my clocks in advance. I do it the next morning.
