But how can I save this way of closing time synchronization by command after system boot up? After I update the system, the first time I start it, time synchronization is still enabled by default. It's not appropriate if I close it alone every time. So when I need it start every time, this function is off. >> >> >> thanks, >> Byron >> >> >> >> >> >> At 2020-04-16 18:28:30, "Kevin P.

We can use timedatectl command to disable NTP synchronize time. But if I flash the system, the NTP synchronize time function will auto enable. so I want modify the systemd and disable NTP synchronize time in default state. >> >> >> >> thanks, >> >> Byron >> >> >> >> >> >> >> >> >> >> _______________________________________________ >> >> systemd-devel mailing list >> >> systemd-devel@lists.freedesktop.org >> >> https://lists.freedesktop.org/mailman/listinfo/systemd-devel >> >> >> >> </pre></div><br><br><span title="neteasefooter"><p> </p></span>
