I spent quite a bit of time digging into this and have discovered that connman appears to be doing nothing in regards to setting the time via NTP. This is on a raspberry pi b+ on a wired ethernet connection. During my search I have founds tons of issues of things like: forgetting to set the timezone, using the wrong NTP servers, connman attempting to use IPv6 for NTP communication, etc. etc. My issue is that connman appears to do NOTHING in regards to NTP. There is nothing in my journalctl about it. http://ix.io/22g2
If I just run `ntpd -n -p pool.ntp.org` the clock gets set fine but is still lost on each reboot. So I can communicate with the NTP servers just fine. Here is my ~/.cache/connman/settings file as well: http://ix.io/22g8
