Wise people have pointed out that there is ntpdate utility that does NTP date sync. Can be installed on raspbian and taken to LibreELEC to be used instead of the monstrous cmd I posted earlier

Attached ntpdate that I've got on raspbian just in case

Seems like no suggestions?

Well, I haven't got to the bottom of this. Tried every possible log/option/idea that I could think of.

I believe the reason is somewhere inside systemd, when it decides that no time sync is needed:

Code

systemd[1]: Condition check resulted in Network Time Synchronization being skipped

Puzzled, I started writing simple NTP client myself, but then found a very nice way to query NTP servers right from the shell.

So I worked around the problem by adding this to .config/autorun.sh:

Code

sh -c 'while true; do date +%s -s@$((0x$(printf c%47s | nc -uw1 europe.pool.ntp.org 123 | /storage/xxd -s40 -l4 -p) - 2208988800)); sleep 3h; done' &

This starts sh in background that loops every 3h. It makes single UDP packet, sends it to europe.pool.ntp.org, parses the reply and sets system time from it. Funny, but this single line works _in place_ of all the systemd+ntpd+settings+headaches+whatever!

So far so good.

HTH

Oh, and this requires having xxd at hand, which LibreELEC doesn't have by default. So I've compiled it myself.

Unzip (forum doesn't allow tgz extensions) then copy to RPI and extract: tar -xvf xxd.tgz

xxd.tar.zip

It turned out that there were not any ntp addresses in the correct gui location.

Thanks for the suggestion.

Yes, I've tried adding custom NTP servers to that list, but that didn't make the trick. BTW, I've read somewhere on the Internet, libreELEC has its own set of default NTP servers, so setting these in the GUI is optional.

What's interesting though is that I don't see it trying any of the custom servers at all. It just ignores this setting!

If that makes additional sense - the issue depends on the networks RPI is connected to. I've tried to use my cellphone Wifi tethering - and it worked normally. Unfortunately, not with my home connection. I've checked every possible setting on the router, but didn't see anything related or somehow linked to NTP. System time on the router is correct - so the NTP is accessible in provider network.

Any chance you have forgotten to enable the "Wait for network" option in the LibreELEC Settings Add-on? A 20 seconds timeout usually does it for Wifi.

Yes, I tried that option (up to 30 sec), but no success

Hi all,

I've been struggling with date problem. It starts, connects to LAN/Wifi but nothing works. Date is wrong and displayed as Apr 2019.

Changing date from cmdline fixes the problem but obviously doesnt survive the reboot.

Checked ntp availability/firewall - everything works as expected. IPv6 doesn't seem to be configured on router.

I can see this in systemd log:

Apr 11 19:28:37 kodi1 systemd[1]: Condition check resulted in Network Time Synchronization being skipped.

but I can't think of anything that I could do to it.

connmand doesn't try to sync the time according to the logs.

No manually configured ntp servers are set in the GUI.

Read tons of time-related posts/solutions but nothing seems to be helpful.

Any suggestions are much appreciated.

LibreELEC 9.2.1 (i've tried latest 9.2.3 but that made no difference)
