As we've been discussing time a little bit recently, I've one remark on
the DM profile.

Clock.NetworkAddress can list an NTP-server for time synchronization.

1) If no NTP-server exists Clock.NetworkAddress, how is that one
represented? NonExisting är some other values? (It might very well
happen that I need to go back and read the full OCPP spec for this).

2) There could be occasions when you want the CP to use NTP, but you
want a DHCP-server to supply the NTP-server address. We need a value to
indicate that situation, e.g. Clock.NetworkAddress=dhcp or auto?
