timedatectl set-ntp is not working

Hey guys. Noticed I had an issue with my clock not syncing.

timedatectl status

gives me

>timedatectl status
      Local time: Mon 2015-06-29 13:42:14 JST
  Universal time: Mon 2015-06-29 04:42:14 UTC
        RTC time: Mon 2015-06-29 04:42:05
       Time zone: Asia/Tokyo (JST, +0900)
 Network time on: yes
NTP synchronized: no
 RTC in local TZ: no

which I guess my problem is the NTP synchronized is 'no'. So to fix it I have tried

timedatectl set-ntp true

however that does not change anything. The

timedatectl status

displays the same thing. the "NTP synchronized" is not changed.

Is that not the correct command? How can I fix this?

Re: timedatectl set-ntp is not working

Check whether the time is getting synced with the NTP server :

journalctl --unit=systemd-timesyncd.service

It does take some time for systemd-timesyncd to sync with the NTP server. You'll probably notice it the next time you boot. Also, try checking /etc/systemd/timesyncd.conf

No messages of syncing, on a different machine I get proper sync messages. However on the other machine I have

NTP synchronized: yes

yet I don't know how to change that on this machine, as the command set-ntp command doesn't change that it changes the "network time on" line, yet the configuration of both machines seem the same otherwise. Just not sure where to look.

Re: timedatectl set-ntp is not working

Could you try to manually restart the systemd-timesyncd.service? Maybe it's trying to sync before the network has been brought up. Also try referring - https://bbs.archlinux.org/viewtopic.php?id=182600

# systemctl restart systemd-timesyncd
