QTimeZone: "Europe/Kiev" vs. "Europe/Kyiv"

l3u_

Hi all!

I'm the author of KGeoTag. This program deals among others with timezone data, particularily a dataset derived from the Timezone Boundary Builder. They write some timezones in a different way than Qt does (the UTC ones are called Etc/GMT), and I map those when creating the dataset.

However I noticed that there's another exception, which unluckily seems to differ across distributions:

On my Gentoo system, there's an Ukrainian timezone called Europe/Kiev (which the Timezone Boundary Builder guys also call like that), but the very same timezone on my Artix machine is called Europe/Kyiv (listed by QTimeZone::availableTimeZoneIds()).

The Artix machine has Qt 5.15.6 installed (the base package is called "5.15.6+kde+r165-1"), Gentoo has Qt 5.15.5.

Is this something that has been changed? I couldn't find a ChangeLog for what was changed from 5.15.5 to 5.15.6. Or: Where does this different spelling come from?

Question is if I have to deal with both versions …

Thanks for all clarification!

@l3u_ said in QTimeZone: "Europe/Kiev" vs. "Europe/Kyiv":

Or: Where does this different spelling come from?

Fro the fact that the russion version is 'Kiev' but the ukrainian one 'Kyiv'.

Qt can not do anything against this - this data comes from the os.

Well, then, I'll have to check which version is provided by the OS and map this entry dynamically if necessary.

Thanks for the clarification!

On linux it comes from tzdata package - see e.g. https://packages.debian.org/en/sid/tzdata

Ah okay, seems like the spelling has been changed with the 2022c release of the timezone data (according to https://www.iana.org/time-zones).
