Hi Folks, My Guix System is configured with (timezone "Australia/Melbourne") which is reflected by the `date` command as well as the Gnome clock. $ date Wed May 15 23:03:34 AEST 2019 In Evolution though, all my calendar events show up in UTC time, so I have appointments showing up at eg. 1am. When I go to Edit, Preferences, Calendar and Task, General, under timezone it says: [x] Use system time (UTC) The timezone can be overridden manually by unchecking the box and selecting at timezone, which fixes the problem but shouldn't be necessary. For what it's worth, the Gnome 3 notifications that show when you click on the Gnome clock are in the correct timezone. Regards, Ben
