I think I found the issue over the weekend on this. I use the NTP device from @dan.t
And there was a version update that I never applied to my test device here at home which changed some of the parameters for how often the query to the time server was done and the drift before updating time. I my test device at home has a 1 minute drift and the one that I deployed had a 1 second interval.
Seeing that I decided to change the drift to a 1 minute interval and see what happens and so far Saturday night, Sunday, and now the A.M Monday everything from my original rule is firing just fine. It may be a coincidence but I going to let these setting sit for the week and see what happens. The NTP server that is running at that location is built into the Asus router and has been reliable for a couple of years now. Keeping fingers crossed.
