Description davidahern 2020-11-02 23:52:37 UTC

SUMMARY
for about a week, timezone was out by two hours.  I have a feeling it happens between when daylight savings happen in Europe and when they happen in US which is the period of a week.  This is my suspicion. It's something i recently observed. And i've noticed this in the past also.

STEPS TO REPRODUCE
1. Observe time after daylight saving time in UK/Ireland
2. It was wrong (slow) by two hours in the bottom right corner of KDE, but correct when i type 'time' in the terminal
3. Observe time after daylight saving time in US
4. Time in bottom right corner of KDE destop is correct... is same as time command in terminal


OBSERVED RESULT
time is out by two hours in weeks between Europe Daylight Savings and US Daylight Savings

EXPECTED RESULT
time should be same in desktop and terminal

Comment 1 Nate Graham 2020-12-01 16:39:47 UTC

If it's right in Konsole but wrong in the clock applet, I suspect a bug in the time provider data engine.

Comment 2 David Edmundson 2020-12-01 23:42:55 UTC

We don't do our own timezone handling, so it won't be our code being wrong.

Please include output of:

ls -l /etc/localtime   
and ~/.config/plasma-org.kde.plasma.desktop-appletsrc

along with which timezone it should be.
