FreePBX polling Time Server every three minutes

My network firewall log shows the FreePBX is polling the time server every three minutes.

Once a day should be ample, is there a NTP polling interval setting I can change?

It is the server not the software polling. It continues after fwconsole stop.

It’s NTP I am sure that polling.

Yes, I’m looking to set the polling interval.

See and .

However, why would you want to do this?
If it’s just the log clutter, I would assume that your firewall can ‘whitelist’ this traffic.
Surely not the bandwidth; even on a slow 1 Mbps connection, it’s about 0.0004%
Or the cost, if you pay a cloud provider $0.12/GB for egress, it’s about $0.002 per year.

Note that if you do a simple daily update e.g. with ntpdate, a system clock frequency error of 0.01% would result in errors of up to eight seconds. If for troubleshooting you need to compare event times between systems, this could be problematic.

Thank you Stewart, cost is not an issue, I was just concerned if this would have been an issue. You (and the links) have clarified this.
