No, the twice-yearly switch is outdated. Energy savings are minimal and the transitions raise accident and health risks.
Permanent standard time makes more sense. It keeps morning light aligned with our circadian clocks, which sleep scientists and groups like the AASM favor for better health and safety. Permanent daylight time means darker winter mornings, which past experiments showed people dislike.
From scratch, set clocks so solar noon is near 12:00 across zones and lock it year-round. No more flipping.
