A more appropriate name for DST is daylight consumption time.  Shifting the clock re-alloates daylight from an hour when most are sleeping to an hour when almost everyone is awake.  And unless our preference for daylight has a discrete jump in the Spring and the Fall, we should be smoothing out this consumption.

Apart from watches (and what is the point of wearing one of those anyway?) nearly all of our timepieces orient themselves relative to a central server.  This would enable us to coordinate a smooth addition of time to our clocks, say 1 minute per day over a 60 day period.

Getting out of bed 1 minute earlier each of 60 consecutive days will dramatically reduce the total level of morning grumpiness compared to the current system where it comes in one big, grumpy, lump.

In the old days when our clocks were not synchronized this would not only have been too much of a chore, it would have caused all kinds of mis-coordination due to lack of common knowledge of the current time.  (Does she worry that I worry that she forgot to add a minute?)  But that problem is gone.

True, there would be a new kind of asynchrony vis-a-vis other countries where consumption of daylight isn’t valued as highly.  Under the current system at least they know our local time modulo the little hand.  But again, their time servers are smart enough to tell them the right time at whatever locale they are interested in.

Then of course in the fall, we smoothly adjust our clocks back.
