NTPを起動できません。 [閉じる]

先週はうまくいきましたが、virtualbox内のVMは5分間同期しません。

$ systemctl status systemd-timesyncd

$ timedatectl set-ntp true

$ cat /etc/systemd/timesyncd.conf

[Time]
NTP=0.asia.pool.ntp.org,1.asia.pool.ntp.org,2.asia.pool.ntp.org,3.asia.pool.ntp.org
FallbackNTP=0.arch.pool.ntp.org 1.arch.pool.ntp.org 2.arch.pool.ntp.org 3.arch.pool.ntp.org

何がこれの原因ですかNTP synchronized: no？

私は64ビットArchLinuxを使用しています。https://wiki.archlinux.org/index.php/Systemd-timesyncd

編集するああ今大丈夫です。
