Hi, Can anyone clearly explain how date/time sync should to work in legato framework? From my understanding it should automatically sync date with network, but for me it doesn’t happen. Ideally device time also should be synced when data connections is established (i am connecting to airvantage).…

I accepted the solution, but it doesn’t mean i’d recommend using it (it’s terribly insecure). However it solves my initial issue. [image] jyijyi: iptables -I INPUT -j ACCEPT

Does this help? [image] How to change NTP server Application that has a call to system(“/usr/sbin/ntpd -p <your ntp server here>”); has to be UNSANDBOXED otherwise it wont work. I can confirm also that: TIME_SERVICES=“ntpd_time” works only if I connect to internet via …

If it’s the same as running (/usr/sbin/ntpd -p ntpserver) in terminal with root privileges - no it doesn’t work.

How about setting it to qualcomm time to receive time from network? You can also check at+cclk?

When we had a problem like this our issue was that not all cellular network providers would have this option to get time from them so we switched to using some ntpd servers and edited the init.d script that updates time. We edited it in a way that it triggers contacting ntdp server only when there …

Thanks for the reply @lazzox Yes it looks like my issue. I would write script but the problem is ntpd -p also doesn’t work. Did you have such issues? Would you mind sharing the script?

@jyijyi , As @lazzox mentioned it may not be a reliable way to sync date.

I don’t see problem, please see below: root@swi-mdm9x28-wp:~# date Thu Jan 1 08:08:44 +08 1970 root@swi-mdm9x28-wp:~# root@swi-mdm9x28-wp:~# /etc/init.d/ntpd_time_service start root@swi-mdm9x28-wp:~# root@swi-mdm9x28-wp:~# date Wed May 6 10:54:21 +08 2020 root@swi-mdm9x28-wp:~# root@swi-m…

Thanks, @jyijyi Unfortunately this doesn’t work for me. Ntpd doesn’t return any error but date also remains incorrect.

Then probably you need to capture wireshark to investigate what happen during " /etc/init.d/ntpd_time_service start"

FYI @jyijyi I got the trace… If i am getting this correctly - server does not respond… Maybe because of incorrect configuration on client side. Request looks pretty weird. Any tips? fx30_time_sync.pcap (611 Bytes) Update: It actually returns a valid date (i stopped utility too soon first time) …
