betlogbet...@gmail.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |betlogbet...@gmail.com --- Comment #27 from betlogbet...@gmail.com --- TL:DR; if you want ISO datetimestamps in regional settings use en_AU as default, and (custom) specify en_SE in Time field. This also makes korganizer work properly (becausue there is no AM or PM). However there is obviously still an issue with en_AU being set globally, as it forces AM to be set as PM. Some time ago I was typing to force systemwide ISO datetime formatting, and did some tinkering with custom locale files. So the AM->PM issue may be related in my case. However as far as i know and can see I removed all said tinkering. Global en_AU is broken when entering AM into korganizer However the below locale settings works just fine. user@betlognuc:~$ locale locale: Cannot set LC_ALL to default locale: No such file or directory LANG=en_AU.UTF-8 LANGUAGE=en_AU:en LC_CTYPE="en_AU.UTF-8" LC_NUMERIC="en_AU.UTF-8" LC_TIME=en_SE.UTF-8 LC_COLLATE="en_AU.UTF-8" LC_MONETARY="en_AU.UTF-8" LC_MESSAGES="en_AU.UTF-8" LC_PAPER="en_AU.UTF-8" LC_NAME="en_AU.UTF-8" LC_ADDRESS="en_AU.UTF-8" LC_TELEPHONE="en_AU.UTF-8" LC_MEASUREMENT="en_AU.UTF-8" LC_IDENTIFICATION="en_AU.UTF-8" LC_ALL= I wrote this before noticing the match at bottom of list... and see that other Australians have same issue I had, so I will paste in case the details are relevant somehow: SUMMARY Cannot set event time to AM Application forces all new events to PM Particularly annoying because my system is set to ISO 24 hour. STEPS TO REPRODUCE 1. create event 2. type 10:00, 1000, or 10:00 AM or 3. mouse select and scroll to 10:00 AM OBSERVED RESULT 10:00 PM is selected EXPECTED RESULT 10:00 AM should be selected SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 18.04 KDE Plasma Version: 5.12.9 KDE Frameworks Version: 5.44.0 Qt Version: 5.9.5 ADDITIONAL INFORMATION kernel version 4.15.0-72-generic 64-bit Due to another issue (inability to remove a personal calendar.ics) I have recently uninstalled, purged and apt reinstalled korganizer -- You are receiving this mail because: You are watching all bug changes.
