I've just adjusted all "old" clocks in the house. 1h+. How will I convince my body and soul that the universe has jumped in time? I have a vague recollection when this winter/summer time change started. But, why... Instead we could decide to keep clocks as they are and get out of bed one hour earlier or later.... It's all down to frame of reference. Are we moving the window or the document. Personally, I'd prefer to keep clocks as they are and make my way out of bed earlier, or later.
