I have code that works for network monitoring OR Time Sync.
When I have both ethernet connections, I can only network monitor. The connection runs through a sharktap so the time sync functionality does not work.
The system necessitates two ethernet connections. One is connected to the sharktap with an Ethernet-to-USB (so timesync functionality no longer works) and the other is connected to the Pi's ethernet port but will not synch time.
I'm building a system to allow power cycling and technicians to remove a USB with logged data that has correct time stamps.
