How to sync the time to network with timedatectl on Ubuntu 18.04?
Solution 1:
From man timedatectl
all you need is to enable NTP-sync.
sudo timedatectl set-ntp true
then it do the rest automatically.
If it does not work check status of systemd-timesyncd.service
systemctl status systemd-timesyncd.service
and restart it
sudo systemctl restart systemd-timesyncd.service
And then check again:
$ timedatectl
...
System clock synchronized: yes
systemd-timesyncd.service active: yes
RTC in local TZ: no
