Nobody really cares, do they? There are much more important problems to deal with in the world.
Than everyone pointlessly redefining time twice a year? Agreed, we could find much better things not to bother doing anymore. Then again, why not get the easy things right before moving on to the harder poblems?
I would have to say that this is one of the rare problems where fixing it results in making things easier for employers and everyone, than NOT fixing it. In other words, the fix results in everyone NOT having to have extra hassle. So if a problem can be fixed in such a way that it causes LESS work than continuing on with the status quo, why not fix it?!
