Action performed: Change the timezone using dpkg-reconfigure tzdata Expected outcome: The clock syncs to the new timezone immediately Actual outcome: The clock doesn't sync to the new timezone until the next minute (HH:00); curiously, if the format of the clock includes seconds (e.g. %H:%M:%S), of if the user hovers over the clock icon, then it's instantly synced, but this kind of behavior seems a bit inconsistent.
This issue was already reported -> bug 9785. *** This bug has been marked as a duplicate of bug 9785 ***
While the two could be tackled by the same workaround (updating the panel clock every second no matter what the layout) in this case we can fix the bug properly as we can listen to timezone changes over dbus through timedated's Timezone property: https://www.freedesktop.org/wiki/Software/systemd/timedated/
Hm the systemd approach will obviously only work for systemd-enabled systems, so no bsds. Let's stick to the resolution of closing as duplicate for now... *** This bug has been marked as a duplicate of bug 9785 ***
