Hi,

I am very new to Qt and just got stuck at a probably very simple problem. The XML file I got contains a date formatted as unix timestamp. How do I get this timestamp into a string?

This is XmlRole:
Code:
XmlRole { name: "date"; query: "date/number()" }
And this is my approach to format it:
Code:
Label {
                id: labelArt
                text: Qt.formatDateTime(Date(model.datum),"dd.mm.YY - hh:mm" ) +"  --  "
}
The result is just the two dashes. Probably the "Date(model.datum)" is not the correct way to do it but I was not able to find how to do in any documentation.

Thanks!

Sorry my mistake. I set up my app in German and change the names to english when I posted the code. Forgot to change the second one as well. In my code that is correct, I use the same name.

[Update]
After a lot of try and error I found the mistake. Date alone was not enough, I had to create a new Date and multiply with 1000 since JavaScript expects milliseconds. Now the code works but I get UTC time. I deducted one hour but I guess that is not the correct way to do it. In case anybody knows how to do it correctly please let me know.

Code:
Label {
                id: labelArt
                text: Qt.formatDateTime( new Date(model.date*1000),"dd.mm.YY - hh:mm" ) +"  --  "
}

After I deployed the app to my Jolla the time zone was correct but on some dates the time is off by -1 Minute.
So I guess this is still not the correct way to do it. Can anyone tell me what is the right way to format a unix timestamp?

Code:
Qt.formatDateTime( new Date(model.date*1000),"dd.mm.YY - hh:mm" )

1397232000 on the other side gives the intended time. I tried to add some milliseconds but this doesn't help either...
