UTC+0, +1, +2, +3 are all correct. But everything starting from UTC+3:30 are all incorrect (1 hour ahead of correct time). I have figured that this is due to a bug in handling daylight saving time. In the US (my current location), daylight saving time will start on March 10, but other regions do not. The digital clock somehow incorrectly assumed that all regions in the world will follow the same daylight saving time rule of the US and so advanced their clocks by 1 hour once their local time is after March 10 2 am (which is when US daylight saving time starts). Freaking daylight savings time. Let's just get rid of it... This is very likely a Qt bug, as we don't do any DST handling ourselves. Possibly even an ICU bug, but I think that's less likely. Please report it to https://bugreports.qt.io/ and then paste a link to it here in the URL field. Thanks! *** Bug 510247 has been marked as a duplicate of this bug. *** |
Created attachment 166834 [details] Correct time is shown on command line, but incorrect timt is shown on Digital Clock SUMMARY The time shown for some time zones are incorrect in Digital Clock. I have tried Hong Kong (UTC+8) and Tokyo (UTC+9) which are incorrect. But I also tried New York (UTC-5), London (UTC) and Moscow (UTC+3) which are all correct. This looks very random. This happens only after I updated to Plasma 6.0.1. (I updated directly from Plasma 5 to 6.0.1, so I am not sure if the bug exists in 6.0.0.) STEPS TO REPRODUCE 1. In digital clock, configure it to show Hong Kong time or Tokyo time. 2. Open the pop up OBSERVED RESULT Incorrect time is shown. EXPECTED RESULT Correct time is shown.
