There's always moans about the disruption to routine caused by the clocks altering by an hour twice a year.
To look at it another way, that's 60 minutes every 180 days or so.
So why not alter the clocks by 20 seconds every day.
Those who think daylight saving time is a good idea will still get their hour difference, those who don't won't notice the 20 seconds. It's a win/win situation.
New digital clocks and watches could be programmed in advance.
Analogue watches are rarely that accurate anyway, so their owners will be used to the idea of constantly adjusting them.
This will make all old digital clocks and watches obsolete, but that's no worse than the digital broadcasting switchover making analogue radios and TVs obsolete.
