WR and system time synchronization
This new feature of v4.2 firmware consist of two issues:
- fixing setting WR time from NTP time in GrandMaster mode (issue 1082)
- setting the system time to WR time in Slave mode.
The latter become important with adding remote logging and monitoring features. To have a consistent set of logs on a central server and be able to correlate them between many WR Switches, we need to have the same WR timescale in all the embedded Linux systems running on the switches.
