My favorite proposal is making days from winter to summer equinox 20 seconds longer and days from summer equinox to winter 20 seconds shorter with 5 days of regular 24 hour time split between the two (6 on leap years). It works out to an hour of daylight savings either way, but it's gradual instead of a sharp transition, and we already have the infrastructure for handling non-24 hour days in the form of leap seconds. For mechanical clocks you'd need to adjust them periodically but typical mechanical watch accuracy is +/- 10s per day to begin with so the change would be barely noticeable.

Of course it's a bit silly, but so is daylight savings in general.

Man, the Romans had this one right. Simply say that from sunrise to sunset is 12 hours (and that much again between sunset and sunrise). Problem solved. No need to worry about more/less than 24 hours in a day.
