Hi Petra,
It's changing time and clocks every six months, not Daylight Saving Time, that bothers me. Supposedly Daylight Saving Time is Ben Franklin's invention - one I'd appreciate year-round. During my early grades in school it was called 'War Time' and continued all winter, so I was 'programmed' for those hours while young and even now seem to sleep and wake on that schedule in winter.
