Besides laptop and desktop systems whose updates may take some weeks; server updates, especially LTS releases, may take months due to slower downstream update processes, plus inhouse corporate testing processes; tablet and phone mobile devices may take weeks or months depending on their priority with the vendor, the telco, and the size of the market in the country for the device; older, cheaper devices (like mine) may only get annual updates, if they are still supported on any upgrade schedule by the telco or vendor. Governments like to think external orgs can provide updates in days, but it normally takes weeks for any official updates, and for older releases months, or never, so may be DIY, by finding something on the internet and trying it! Especially so if the country in question has a population (AKA market) less than some cities, or for some island nations smaller than large towns! As a workaround fallback, users may select the zone below (extracted from zonenow.tab) until updates are made available for their system: -03 America/Sao_Paulo eastern and southern South America -- Take care.

It seems this is totally a thing about version release schedules. It was way too soon to declare a change like that on my country's part.
Thanks a lot and your work maintaining this is highly appreciated :)
Cheers, Martin Vuyk L.

A lot of systems went crazy [in Paraguay] because some changed the timezone [this past Saturday evening] and some didn't. I have some headaches at work already on a Sunday (yay). AFAIK this database is the source of truth for most systems. But I don't know how fast you could change this and it getting pushed to all devices.
All— The recent change for Paraguay (staying on -03 and no longer falling back to -04 from 2025-03-22 24:00) was made to our development repository in the following commits dated 2024-10-05 and 2024-10-15: https://github.com/eggert/tz/commit/636e6f983bca35e6f945e092ffdc315ae3e5dd9e <https://github.com/eggert/tz/commit/636e6f983bca35e6f945e092ffdc315ae3e5dd9e> https://github.com/eggert/tz/commit/486e1e890e68d52f9236b2b354484463f57ec692 <https://github.com/eggert/tz/commit/486e1e890e68d52f9236b2b354484463f57ec692>
