I looked at this commit, which adjusts some transitions for KZ. After looking closer to diffs I found out that formats of zones are changed, e.g. for Asia/Almaty it changed from ALMT to +06. I'm not familiar with TZ files, but I suppose this changes are the reason of incompatibility for some apps.

After upgrading tzdata to 2016d version some of applications unable to determine right timezone for all zones which belong to Kazakhstan. I personally use Asia/Almaty (which is +06:00 and no DST) on my machine (Arch Linux with Plasma 5.6), and it leads some programs to produce unexpected results. E.g.: Digital Clock applet shows -12 hours from current time and Plasma Lockscreen shows time in UTC.

I'm not observing this problem on Fedora 23 (2016d-1.fc23) with gnome-clocks (3.18.0-1.fc23).

Other users have reported problems with the Plasma Digital Clock applet after earlier tzdata upgrades. See for example:

The first thread says that a relevant bug was fixed in plasma 5.5; are you running that version? If not, I suggest upgrading. If so, perhaps there are other, similar bugs that haven't been fixed yet.
