Solar noon and local noon are different things, unfortunately. Changing an offset isn't quite the same thing as changing the measure of a unit. Seconds, minutes and hours are not being adjusted as part of this. It would be more like starting to count from 1 metre instead of 0 metres to adjust the length of your commute. > Business hours are almost entirely arbitrary anyway. Change them instead. As it happens, a sibling comment has already pointed out that people have effectively done this. The time of day you eat lunch is arbitrary. So the lunch hour in Spain is 14:00 instead of 13:00, effectively resolving the 'wrong hour' issue.
