Daylight savings not correctly applied in qml about pkgbuilds HOT 5 CLOSED

another distro

Which one exactly would be good to know? And I assume you're also referring to the mingw-w64 package provided by that distro?

Can you provide a small demo project to reproduce?

I assume you use the regular, dynamic version (mingw-w64-qt5-base package)?

Sorry for the delay, I had a very busy weekend away from the PC.

I now use Ubuntu with MXE, which also uses mingw-w64.

I threw together a simple test qt-app:
time_test.zip

Yes, you assume correctly.

In my case this issue is different. At least when testing with Wine:

In the background is the correct value (native Linux build) and in the foreground the Windows version started with Wine. So the time and Date.getHours() are even correct, but in the timezone the daylight saving is also missing.

Hard to tell what's causing this. I can't find any patches in the MXE which would fix this. I also doubt my own patches introduce any bugs regarding this. Yes, there are many patches, but most of them are about finding dependencies and other build system issues.

And in my case it is also just a QML issue. QDateTime works correctly. Eg.:

cout << "Qt: " << QDateTime::currentDateTime().toString(Qt::RFC2822Date).toLocal8Bit().data() << endl;
cout << "daylight saving: " << QDateTime::currentDateTime().isDaylightTime() << endl;

prints:

Qt: 07 May 2018 22:39:53 +0200
daylight saving: 1

That is weird with only the toString() being off. Though QDateTime also worked fine for me. So yeah, it is only a QML issue.
Interesting enough though, I once tried to supply the date through an interface into QML as a QDateTime and even then it had the same problem. So I would suspect the error being in the javascript engine and the Date type.
I don't know if I have some time to dig deeper into this, but if I do I will let you know what I find.
Thanks for your help!
