Not really. The equilibrium of removing daylight savings will result in schedules somewhere between DST and Standard Time. This just gets you there faster.
The trade off of having 30-minute time zone offsets probably isn't worth it, but this solution isn't immediately "stupid."
Actually the only intelligent solution is to abandon discrete time changes to & make this a continuous adjustment. We need to adjust the clock continually, ongoingly, to appropriately track the light of the day.
