Quick question, because I've followed a number of how tos before that don't, if you disconnected all network connectivity, would it sync to the PPS source? Second, have you tested this, I only ask because 1# I found a lot of time sync was really slow, and #2 some of them reported that they had sub-microsecond time sync but when tested they were several milliseconds out.
Anyway, I solved these problems with sbts-aru, but maybe it's interesting for you to test if you haven't already done this.
