In fact, you actually have to be pretty careful about changing the times in this fashion. If you advance (or back) the clock by a large amount (~5 min), you have the annoying tendency to break DECNET momentarily. This seems to be a problem in scheduling routing packets. When the clocks get changed, sometimes the packets don't arrive within their timeouts. The node suddenly drops off the net for no reason. The trick is, of course, to apply frequent smaller changes. ;-)
