I believe that I've just found a bug.
In https://github.com/lede-project/source/blob/master/package/utils/busybox/files/sysntpd
it use PROG=/usr/sbin/ntpd
However, the program is available under /sbin/ntpd but not /usr/sbin/ntpd.
and it does not accept argument "-S" .
Only ntpd 4.2.8p9-2 is installed.
No ntp-utils, ntpdate, nor ntpclient is installed in my system.
Uninstall of ntpd seem fix everything.
It feel like ntpd is broken and it should not broke sysntpd.
Well /etc/init.d/sysntpd is the init script for busybox' builtin ntp server. If you install a standalone ntpd, it should ship its own init script (/etc/init.d/ntpd or similar).
There was no /etc/init.d/ntpd.
Even so, installation of ntpd should "disable" not "broke" sysntpd
same problem here. I think - it was working fine until I installed: luci-app-ntpc and ntpclient
since then the ntp server is no longer working on the device. I removed ntpclient again, tried it, and also switched to ntpd and ntp-utils without any luck.
default config. I saw some entries in the logs regarding the command line:
/sbin/ntpd -g -u ntp:ntp -p /var/run/ntpd.pid -n -c /var/etc/ntpd.conf
still - there is no ntp related process running, port 123 is not in use, and there is no service responding to any ntpclients from the network.
If I start that command line listed in the logs, everything works as expected - but starting it from the startup section, does not yield any new processes or error logs.
this is how i check for listening ports:
netstat -Wpn -l -a | grep :123
config /var/etc/ntpd.conf
driftfile /var/lib/ntp/ntp.drift

I tried the default and the modified configuration - both only works if I start the process manually - but both fail to start automatically or via the uci startup interface.
What version of OpenWrt and ntpd?
OpenWrt 19.07.3 r11063-85e04e9f46
ntpd 4.2.8p15-1
I use chrony, it's smaller than the ntpd suite.
If you are using ISC ntpd, then disable BusyBox sysntpd to avoid conflicts:
/etc/init.d/sysntpd disable
/etc/init.d/sysntpd stop
/etc/init.d/ntpd enable
/etc/init.d/ntpd start
Unfortunately, no change.
Also: is the luci function under system>startup doing something different?
Try to avoid using interface/socket binding.
Mmh. Ok
I removed that and started again. Still no processes running and no errors in the logs
Post the output:

/etc/init.d/log restart; /etc/init.d/ntpd restart; sleep 10; logread -e ntpd; \

Also, i don't understand the init script. It seems to reset the ntpd config file when starting an instance but the file remains unchanged. I don't know how to debug that 
If that helps: the directory /var/lib/ntp/ is empty. Even stays empty if i start that command manually.
Enable the UCI section and add the NTP servers:
uci set system.ntp.enabled="1"
uci set system.ntp.enable_server="1"
uci -q delete system.ntp.server
uci add_list system.ntp.server="0.openwrt.pool.ntp.org"
uci add_list system.ntp.server="1.openwrt.pool.ntp.org"
uci add_list system.ntp.server="2.openwrt.pool.ntp.org"
uci add_list system.ntp.server="3.openwrt.pool.ntp.org"
uci commit system
/etc/init.d/ntpd restart

https://github.com/openwrt/packages/blob/master/net/ntpd/README.md
Note that the /var config is runtime, so do not edit it.
That's it. I didn't read the readme
Everything is working now. But it says it's 4am already.. so i better go to bed now.
Thank you very much for your help.
