I've always used UTC for persistence and let the frontend handle the presentation. Worked 100% of times. Brazil has too many timezones to let this be a problem for government systems on meetings.

i do not understand, maybe some of the readers here can explain to me how
"wake up earlier and have more light at the end of our social day".
and
for better entrainment to solar exposure.
Because it is true? My body clock tells me to go to sleep at a certain time of day, and then the wake-up clock tells me when to awaken. When I have to adjust the clock, that means one hour less of sleep.
So if studied academics bring arguments like [2] does, "-1 hour sleep!", then i wonder. How about being *conscious* about the living situation, and go to bed earlier?
Yeah, good luck with that.
The *solution* is of course to set the *wake-up* signal to one hour later, and to shift office hours by one hour forward, so to get in to office at 9 am instead of 8 am during DST. That's the only way to properly cope with DST-related jetlag that I have found so far (I have tried, it works very well, the only problem is coping with other people expecting you to be in early).
My main gripe is the morning dusk. It's of course not a real problem in summer, then I don't care if sunrise is at 4:00 or 3:00, because I will be asleep by then, but now that we are *just* getting daylight at wake-up we're about to set the hour back an hour, so that we again have to wake up to the despair of blackness. That's the problem.
My gripe is more with sunset. Here in Massachusetts, USA "Eastern Time", the day before the "DST fall back" it's dark around 5:30pm, and the next day it's pitch black at 4:30pm. I hate that. Plunged into 'despair of blackness' (I love that phrase. :-)).
I find it curious how we all live by the clock on the wall rather than natural daylight. This of course makes sense since the whole point of civil time it to "coordinate activities", But DST basically makes no sense. Why do we need more sunlight in the afternoon in summer when we naturally have more sunlight in the afternoon in summer? If later sunset is the objective it would make more sense to have DST in the winter. But that's not how it's done. DST causes trouble for somebody at both sunrise and sunset.
I wonder what might have happened back in 1973 if the USA had gone to "permanent standard time" rather than "permanent daylight time", which was was quickly repealed. Maybe "permanent standard time" would have held?
There are many discussions of DST, ranging from energy to safety to sleep patterns, etc.
There are two aspects I think do not get enough attentions that argue for "permanent standard time":
1) local timekeeping as per TzDb and downstream systems, where introduction of "permanent daylight time" causes technical difficulties, confusion, and likely unnecessary expense.
2) Some USA federal proposals for "permanent daylight time" actually alter the terms of the 1918 "Calder Act" and the Uniform Time Act of 1966. It seems to me this must have important legal ramifications for nearly every document and procedure that relies on a date and time. Does a change like that alter the meaning of every contract, transaction or schedule ever issued?
