The major advantage of NTP syncing your routers is that it allows you to
more effectively correlate any log messages that these devices emit to
log messages other devices generated.

Did two events happen at separate times, or was it perhaps the same
event at the same time? the incentive is ease of troubleshooting.

on this topic, i strongly recommend to operate all devices in the
Etc/UTC timezone, this makes coordination with external entities much
easier.

Kind regards,
