Tell HN: The 10-bit timers are about to overflow on September 17th
Here are a few links. This is the key one.  The units with this problem are obsolete and Microsemi has done very little to publicize this.  This means you have a ticking time bomb if you thought everything was good because you got through the 2019 rollover.  There are a few select models where a return-to-factory firmware update can help you dodge the problem, but it is probably too late to get something turned around now if this is the first you have heard of it.  If all you need is a 10 MHz or 1PPS reference, those bits will continue to function.  If you need it for NTP, you've got a problem.https://sync.empowerednetworks.com/keep-your-ntp-server-curr...Another link stating "But other GPS receiver manufacturers set a delayed date for the rollover date to occur on – September 18th, 2022".  "Other" in this case = Symmetricom / Microsemi.https://www.orolia.com/will-your-network-time-servers-be-aff...
