time
systemd
Set time to synchronize with an ntp server:
timedatectl set-ntp true
This info stays in /usr/share/zoneinfo
.
Local Time
Local time is kept in /etc/localtime.
According to Dave’s LPIC guide, you can set the local time by making asymboling link from your timezone to /etc/localtime, as so:
sudo ln -sf /usr/share/zoneinfo/Europe/Belgrade /etc/localtime
…however this produced the wrong time for me. Further, /etc/localtime produces an output with cat, while the zoneinfo files do not.
Locale
See local time, language and character settings with:
locale
List available locales with:
locale -a
To see additional locales which are available (but not necessarily installed):
cat /usr/share/i18n/SUPPORTED
Set a supported locale with:
locale-gen pl_PL.UTF-8
Then set that language, with:
LANG=pl_PL.UTF-8
… then reboot.
Network Time Protocol
Glimpse an overview with:
ntpq -p
Usually this is run as a service, so just start that service.
Force Reset
If your clock drifts too far from the right time, it will not reset happily. For it to reset like this:
sudo ntpd -q -g -x -n
