+# 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
+
+Enter the shell with:
+
+> ntpq
+
+Or just glimpse and overview with:
+
+> ntpq -q
+
+This clock can drift, which is then listed under /var/log/ntp.drift
+
+The config is under /etc/ntp.conf.  If a line for the stats directory is listed, it'll log stats, e.g.:
+
+`statsdir /var/log/ntpstats/`
+
+This can show if clock drift occurs.
+
+The config file also lets you specify servers to obtain time from.
