We have few PMP450m Access points at our site.We don’t have any NTP server. For clock pulse we have installed cnPulse. What is the reason for PMP450m system time is 9 minutes differ then actual time as shown in attachment. All PMP450m AP’s and connected PMP450i Subscriber having the same issue.
What do you have in
Home → GPS Status → GPS Time?
and what in
Configuration → Time → “Allow GPS to set System Time”?

Interesting, I’m aware of old hardware giving bad dates but not exactly 9 minutes off. So, I suspect an issue with that GPS hardware sending the wrong time.
In general, I would recommend shutting of “Allow GPS to set System Time” and setting up NTP.
I suspect no NTP and “Allow GPS to set System Time” disabled.
