I’m not aware of the time being available via RTDE, I looked at the docs again and all I see is the actual execution time but I’ve never queried that so not sure exactly what that is. 
As as far as logs, the only place I know you can get them from the stream is via port 30001 and you have to decode the stream to get them.

                We don't use Python but here was a library that I have looked at in the past that may be helpful.  This is a link to the file where I believe they are doing the decoding of the data stream from port 30001.

Can I know the robot uptime using RTDE communication?
