NTP - Time Server Sync Frequency
Pfter checking my router logs, it appears that the router is synchronising the time with the Netgear NTP server every 30minutes & sometimes only 5minutes after a sync. Is this expected ?? 1 time...

No, completely wrong. The NTP time sync happens every time the router does connect to the Internet successfully. Best guess, you use an Internet onnection requiring authentication, and the router is configured with a Idle Timeout and Connect on Demand. This is wht kills your Internet connection, and when the next time Internet connection is required, the router does dial-up, and the NTP time sync follows.
My RAX80 does that also.
Every 24hrs and on power up would be a more normal interval to check the RTC is accurate.
I did report this issue a month or so ago but like most problems with the RAX80 they don't get fixed.
My one is no longer in use and I have gone back to my old one.

If you get the pairs of "[Internet connected]" and "[Time synchronized with NTP server]" your router does (or did) connect to the Internet only if traffic is requesting it. Otherwise the connection does timeout as configured. The reason why it does happen - unless you have a router that is crashing and rebooting - is very clear, and not an issue.

That's what is implements, and what Netgear routers commonly do:

Do the internals clocks really need setting that often?
Still their product in recent times have been pretty poor.
Powered up the old RAX80 again and here is the log (after I cleared it).

[Log Cleared] Monday, Nov 04,2019 18:54:36Only set the time twice in a few minutes and no internet reconnections.
It is just very poorly of programing and Netgear should be ashamed of themselves.
