Time 同步

使用 Manjaro，最近发现时间不同步。Manjaro 目前使用 systemd-timesyncd 服务同步时间。可通过下列命令查看服务状态：

1
$ systemctl status systemd-timesyncd.service
2
○ systemd-timesyncd.service - Network Time Synchronization

　　可知时间同步服务器访问出现问题。修改服务器为中国区的服务器:

　　sudo vim /etc/systemd/timesyncd.conf

1
[Time]
2
NTP=ntp.aliyun.com ntp.ntsc.ac.cn

　　重新运行服务，或者手动更新

1
# 手动更新
2
sudo ntpd -q -g -p ntp.aliyun.com

1
# 重新运行服务
2
$ systemctl status systemd-timesyncd.service                                                                                                                ✔
