IDnpTimeSource Java wrapper is not available

[nicolatimeus]

Currently there are no Java bindings available for the IDnpTimeSource class.

This prevents Java OutstationApplication implementors from overriding the behaviour of the default IDnpTimeSource::Now, which always returns an invalid timestamp with 0 as value.

A Java DnpTimeSource interface wrapper should be added and OutstationApplication should extend that interface to match C++ API.

Good catch. We'll add this to the develop branch and also back-port it and do a 2.x series release.

This was implemented in the develop branch for both Java and C#, but introduces a couple of breaking changes, so I won't be merging it into 2.x for now.
