The answer (for software engineering) is to stop thinking of time as a continuous flow with periodic markers such as second, minute, etc. Instead, think of it as chunks. Mostly one chunk flows seamlessly into another. Occasionally, a chunk is "missing", such as skipping an hour at Daylight Saving. We are already set up to handle that. It would be very simple to add another rule to the DS database to globally add a second now and then. I really don't see what the problem is.
