Set up Time Synchronization on Linux

First step: Check your current data time
- $ date
- Wed Feb 28 03:54:59 PM UTC 2024
Change your time zone
- $ dpkg-reconfigure tzdata
- Current default time zone: ‘Asia/Bangkok’
- Local time is now: Wed Feb 28 03:58:13 PM +07 2024.
- Universal Time is now: Wed Feb 28 08:58:13 UTC 2024.
Check NTP status
- $ systemctl status ntp
- $ ntpq -p
Alternative: By systemd-timesyncd
- $ systemctl status systemd-timesyncd
Finally
- $ timedatectl
- Local time: Wed 2024-02-28 16:02:19 +07
- Universal time: Wed 2024-02-28 09:02:19 UTC
- RTC time: Wed 2024-02-28 09:02:19
- Time zone: Asia/Bangkok (+07, +0700)
- System clock synchronized: yes
- NTP service: active
- RTC in local TZ: no
