Hi All, In our IoT project we have to select an NTPd for our embedded device in order it can have accurate time. It uses 3G/4G mobile net. Of course the net is expensive so we have to reduce the network usage. Currently we have 2 candidates : OpenNTPd and Chrony.
In OpenNTP (5.7p4) we are missing some features and we are looking for some solutions or workarounds to provide them. Do you have any idea how to do it with OpenNTPd : * Maxchange Maximum allowed offset corrected on a clock update. If the delta is bigger ntpd exists. * Polltime maxpoll /minpoll : setting the minimum/maximum polling interval * Offline mode You tell the ntpd that network is not available. So it will not keep trying to connect to ntp servers. Kind regards, Gabor Juhasz
