Worldtimer: Leave at UTC or Adjust for Summer?

For those with worldtimers who live in countries which implement Daylight Savings Time, Summer Time, etc., I'm curious. Do you leave your worldtimer set to UTC year round, or do you adjust it for the summer?

In either case, you have to mentally keep track of which locations implement summer time and which do not so that you can account for that appropriately. I realize that the Aqua Terra uses different colored text to delineate the two, but that's not necessarily time-zone wide, rather it's only for the indicated city/country. I'm not aware of any other watches that accommodate summer time. (Well, accept for the Apple Watch. Its world time watch face changes the displayed numbers on the 24-hour ring to match the actual local time.)

FWIW, I adjust mine. Otherwise, it would seem weird if my time zone's time didn't match local time.

I'm a bit confused.
If you use your 24HR hand for UTC, it doesn't change. There is no daylight savings time for UTC.
If you're using the 24HR hand for a remote location, you may have to change it to that location at changes from daylight to standard etc.

Here's a specific example:

If I leave my 24HR hand set for UTC, then, when I look at, for example, New York, the time it shows for New York will correspond to Eastern Standard Time. But New York isn't currently on Eastern Standard Time, it's on Eastern Daylight Time, so the watch wouldn't actually show the local time in New York.

But if I adjust the 24HR hand to accomodate daylight savings time (which I do), then the time the watch shows for Cairo, as an example, won't be correct.

I can see how changing UTC would remove the need to mentally account for DST in local time zones but it just seems so wrong. UTC is the standard it should never change. Of course, do whatever you like best!

Changes to civil time zones are crazy to keep up with, several revisions to the database every year. Some years ago I had to explain to a friend whose job included maintaining the time zone data for Solaris, then a fairly major operating system, that I could not confirm to him when the UK's DST would start because at the time it was decided after debate by Parliament and they had not yet got around to it. Dead-tree diaries for the year in question had no entry for BST start or finish either. I am someone who always gets the local time by looking the ticking device on my wrist, but for the time in another country my phone is far better at it.

Time zones become very fun when working with computers!

Even more fun when working with stock markets when exact time of a bid makes, or does not make, the deal. Not my actual experience, but I did go for a job in that field and did some research. Less than milliseconds on a connection that needs to be encrypted, go hallway round the world and then be decrypted. Tricky stuff.

If the US Senate's bill becomes law, and the U.S. goes on Daylight Savings Time permanently, a lot of Worldtimer complications are going to look weird if set to UTC. Many watchmakers have already dropped Chicago from the complication in favor of Mexico City. Maybe it would be time to drop New York, Denver, and Los Angeles as well.

I set mine to wherever the biggest Killing Kittens party happens to be going on.

Timezone variations means that worldtimers are decorative, not functional. There's no way to set it to have it be accurate. It's an interesting idea, which doesn't work, but which is still popular because people like the way they look.

For the JLC Geographic, it is possible to alter the difference between cities on the 2nd timezone subdial. I often changed this, due to DST variations.
