UTC offset reported incorrectly after setting time zone first time

[Selene ToyKeeper]

After a fresh install of Ubuntu Touch, one of the first things I want to do is set my time zone. If I do this, it works, but the display is odd until I quit the settings app and restart it. More specifically:

- Drag the clock indicator down, and tap time/date settings.
- Tap "Etc/UTC UTC+0" and set the time zone to Denver.
- The Time & Date settings app now shows "America/Denver UTC+1", and the time shown a few lines down lists a time which isn't correct. However, the clock in the upper right has the right time.

After this, if I quit the settings app and come back, everything is displayed correctly (currently UTC-6).

Thanks for the bug report, indeed the utc offset is displayed buggy (can be reproduced on a desktop as well)

This all works correctly in our last promoted image (237), which uses Qt 5.0 still. I strongly suspect it's a change/bug with 5.2.

Can you confirm which image you were using, please?

Laney, I agree this may be a change related to 5.0 --> 5.2. This bug is consistently reproducible in image 257, which has Qt 5.2.1+dfsg-1ubuntu10

[Iain Lane (laney)]

Yeah, I can't blame u-s-s here. We could do some terrible thing like call timeZoneUpdated() (or the correct name) until it's correct to work around the problem...

Ah, sorry. I put the revision in a tag but forgot to put it into the main bug description. I confirmed it in image 249, but I've seen it pretty consistently since then too.

Still happening on image 261.

I've identified a Qt fix for this bug, and I'm in the process of sending it upstream now.

This bug was fixed in the package qtdeclarative-opensource-src - 5.2.1-3ubuntu12

This seems to be fixed in image 276 and probably a few before it.
