I am using openSUSE 13.2 (Harlequin) (i586) and KDE
The time displayed on the taskbar is two hours more.
If I right-click and choose “Set date and time” a frame will appear with the right time. Nothing to do.
If I try to set the time for YaST, then the time is right. Nothing to do either.
The Time Zone is set correctly for Brazil and I am using UTC.
See below an image with the window of adjustment and clock in the taskbar
What should I do to make the taskbar clock shows the correct time?
Check:
ls -l /etc/localtime
and
echo $TZ
That’s the results
sergio@linux-xgwm:~> ls -l /etc/localtime
lrwxrwxrwx 1 root root 37 Fev 3 07:03 /etc/localtime -> /usr/share/zoneinfo/America/Sao_Paulo
sergio@linux-xgwm:~> echo $TZ
sergio@linux-xgwm:~>
echo $TZ returns nothing
As you posted everything correctly between CODE tags. I see what it returns. And the last command does return an empty line, which is NOT the same as “nothing” (remember this is about computers, thus preciseness is all important) 
May be I should explain a bit. The TZ environment variable may contain a time zone. E.g. a user may want to live in another timezone then the default onee of the system (remote login from around the globe). When it is empty or non existent (as here), the symlink of /etc/timezone is what counts.
So no surprises here.
Maybe you can also check what the time/timezone of your session at that moment is by just displaying it:
date
BTW, I have to shutdown and leave in about an hour. I hope others will join to help you.
The result of “date” is correct. But the clock in taskBar continues with two hours advanced
sergio@linux-xgwm:~> date
Sex Fev 3 10:17:17 BRST 2017
sergio@linux-xgwm:~>
the others will diagnose problems, but i had a run around for months changing time zone using the clock dialogue. Eventually realised you have to set the time and zone using YAST!

Make sure you don’t have a different time set within the clock widget
itself.

That also looks fine. It seems that all applications then get the correct settings. Thus the widget seems to be incorrect. I do not know the widget, thus I can only recommend @kench’ suggestion.
How do I make sure that I do not have a different time set in the clock widget?
If that means clicking with the right button on the taskbar clock and adjusting the parameters offered, then I already showed in the image above that there is nothing to adjust.
This is a mystery.
I clicked “Bold” in the configuration window below and
1-As expected, the source into clock is turned to “Bold”
2-Instead of showing “UTC”, now started to show the date
3-The time was correct.
I do not understand why this happened, but the problem is solved.
Thank you all.
Sorry I did not answer until now, but I was on a holiday.
Nice it is solved, albeit on a unsatisfying way. Seems to be something in KDE and you could go to their forum/bugzilla. But OTH, I personaly am afraid that will not be of much use.
