I don’t commute across time zones, but where I live is very rural and most things I need to travel east to nearest city almost 2 hours away. I may get better at it if I did it daily, but it is awful. I find it easiest to just add an hour to my travel time, but I also back myself up with entering a calendar event in my phone and setting the time zone. That being said, lots of people miss flights and other appointments. My wife missed my son’s dental appointment just last week
