Check system time, time zone and NTP sync

harmlessSystem and hardwaredebian, ubuntu
user@server
timedatectl

Shows local time, UTC and RTC as well as the configured time zone. The important lines are System clock synchronized: yes and NTP service: active; otherwise the clock drifts. A deviation of a few minutes is enough to make TOTP codes, Let’s Encrypt validation or log analysis fail.

Note: With systemd-timesyncd, timedatectl timesync-status shows the server and offset. With chrony, chronyc tracking provides these values.
