Hi,
To my understanding, the key point is when the time is configured on
the router. The line will be generated by the router. I tested it on
my router with clock set, not even ntp master. For the stratum thing,
I guess you should get the same result if you can make the router
thinks the time is synced and valid.
Regards,
Edward Lui
