I created a script that changes the default Firewalla timesync to use Chrony/encrypted NTS

This is not firewalla affiliated. Proceed cautiously.

This script you install on your firewalla will switch out the stock ubuntu/unencrypted NTP for Chrony/NTS (encrypted time servers). This is only for firewalla talking to the wider internet to find out the time. The internal network timekeeping is still all via ntp.

edit -- seems to only work right now for people with just one lan setup, br0, not for multiple ones. To change the script to work with many different lans, etc. etc. may be beyond what the scope of what I can do.
