I don’t know for sure, but on a different thread we discussed setting up an NTP server for a local network, using a RPi, SignalK, and the plugin. Sailoog decided he could easily add that as a feature to Openplotter. You can find it in the settings app. However, for a NTP server to be accurate, the time needs to be adjusted regularly, so I bet Sailoog made the change to accommodate the NTP server.
I’m sure you can set it back to “0” and turn off the NTP if you don’t need it.
