There's an idea - sierra MC series 3G and LTE modems also have GPS output accessible to routerOS... I reckon it should be possible to script a clock update based on that GPS data....? Cheers!

You can get GPS based stratum-1 clock (commercial types) which are not at atomic clock prices but do a very good job. I think I remember seeing a Pi based roll your own GPS Stratum-1

Yes, but *it* will need to get sync from somewhere else too ;)
I think I need my own atomic clock! :-D
Cheers, Mike.

Mike,
Perhaps a Raspberry Pi would be suitable for acting as an NTP server running NTPD or OpenNTPD. Cheap and cheerful!

Good question!
This one uses script to pick a new NTP server from pool.ntp.org every week - so I don't have a record of what it had configured when it went to sleep :-}
Although it's not exactly a mission critical router, this event is probably a good lesson that I should find some alternative method to keep track of time ;)
Cheers!
Mike.

Hi Mike, What version of NTP is it talking to. I have just looked at 8 CCR's all up and running but all say
At the same timeing. Nothing froze however all going strong. (so far) we are running 4.2.2 on our NTP server.

Hi,
It wasn't just you! ;-)
It also happened to just one (of many) of ours - CCR1009 rOS6.28
Fortunately, it was the one in our rack right downstairs - so easy to access and power cycle. Would be real bad if it happened on one of the others, since it was well and truly hung... only power cycle would recover it :( Cheers!
