Hi Marcel If you need any extra help in this let me know. I did look into integrate NTP into connman but then I went into sabbatical and forgot about it.

And I am also looking at GPS time and also NITZ. So ConnMan will become the central point for time updates. As long as you select automatic time updates it should utilize all available resources to have the most accurate sense of time without consuming too much CPU cycles or network bandwidth. We are clearly not there yet, but I am convinced that only a full integrated solution that knows about real online/offline states will work here. I have a proof-of-concept for Simple NTP working and Martin volunteered to help integrating it. I will commit this after we have done the next release. When it comes to integration with Gypsy, we have to look into it. I have not at this point. Mainly because NTP is a way better sources when you are actually online. Only when you are offline, GPS and NITZ are useful. > I am mostly looking at this from an IVI point-of-view but I guess these > questions may be relevant for other devices too. I can see your point here. In the IVI case you rather wanna have GPS and NITZ since you most likely will be more offline than online. So seems like ConnMan needs a plugin to interact with Gypsy. I still need to get a bit deeper into GPS since for time concerns we might not have to wait for 3D fix. So the power consumption on systems were the GPS is most of the time off is interesting.
