Thanks @sw2090. I'm wondering if, having learnt the time from a PTP source the Fortigate can advertise that time via NTP. When I use the GUI, selecting PTP causes the NTP options to disappear. Is this just the GUI assuming things or a constraint of the underlying system?
My PTP feed is due to arrive shortly and I'll do some testing then, but was wondering if anyone had walked this path before me.
