So many issues you can run into with time! One that really annoys me is the Health app on iPhone, where it records step count and other data, and does it well if you stay in the same timezone.
But when you change timezone, the data is shown in the zone you’re in now (I assume it’s stored in UTC and then converted to the current timezone). Which is technically correct, but then looking back, it looks like I was doing a whole lot of walking from 9pm to 11am for a few weeks while I was on a trip (it was actually just a regular daily schedule), which then messes up the daily average step count, because the day boundaries aren’t what they actually were there.
I’d really rather have an option to show it in the timezone that I was in at the time, and then on the daily resolution graphs mark where the time zone changed (with the hours in the difference either skipped or repeated depending on which way).
