Here's a solution for you. Universal coordinated time. UCT is the same time around the world. You don't have to ever change what time it is.
Fuck it - let's go epoch time all around the world no more DST, no stupid 720 degree clock or timezones. While we're at it - let's get rid of days of the week, month and years as well. It's 1791452533 right now, I'll see you at 1791452533.
I'd say another drawback to getting rid DST is that any tradesman working outside would have to start banging hammers an hour earlier to miss the heat of the day waking people up whilst construction projects miss an hour per day, per person, per project because exhaustion leads to fatal work accidents.
Then there is the additional energy consumption required for lighting in the evening that would have been provided by the sun for free.
