16:17:57 SNTP Synchronised to server: 212.159.6.9

This seems somewhat excessive - surely once a day would be sufficient!

At any given moment in the universe many things happen. Coincidence is a matter of how close these events are in space, time and relationship.

Does anyone know what the overnight usage with the 585v7 or v8 is if you stay connected but no PC's on etc midnight to 0800 ?
I thought someone posted a figure somewhere a while back and I thought it rather high compared to my meagre 61.02KB but my Voyager doesn't talk to time servers so this may have something to do with it.

I'm not sure why it does it this often. As with all Thomson/Technicolor units, all this can be programmed, including the NTP server and frequency.
At one per hour, you are talking around 100KB per month in total.
If you wish to change this to something like once every 24 hours, this can be done with the following command in telnet
:sntp config poll=1440
Note: I've not done any analysis on time drift on the unit, so not sure if the routers clock is susceptible to issues.

I didn't 'saveall' so the modification will be lost on restart, but not anticipating needing that. The router has been up 19 days at the moment.

Hi spraxyt,
Just in-case you wonder why this change isnt reverted on reboot, an equivalent 'saveall' command is run on the router every 60 seconds.
You can configure this by changing the autosave and autosave delay parameters which can be viewed by running the command
:system config

As you said my router has autosave enabled and autosavedelay=60s.
Router time remains spot on 9 hours 30 minutes since the last sync in the early hours. I've now changed the polling interval to 1440 minutes (24 hours).

If the TG582n behaves similarly can't see any reason why time syncs need to be done more frequently than once per day assuming it's unlikely that ntp.plus.net will fail to respond.

I did once have a Buffalo router that had an NTP server feature so I allowed that to sync off the internet then synced my local PCs from the router but I assume we all sync our PCs direct off the internet nowadays.

It ought to be - the time service appears to reside on the DNS servers so if none of them are responding there are arguably bigger concerns than clocks drifting.
