The AMM can act as a Network Time Protocol (NTP) server for use in highly restrictive private network situations where NTP is not available internally nor from the Internet. For example, a gateway must rely on GPS to obtain the time when powering up. However, GPS is not always available (e.g. because the gateway is under cover, on a test bench, etc.) and if the unit has been off for some time it, will not report events properly to the AMM until the time is corrected. In such cases it is typically easiest to get NTP directly from the AMM. AMM NTP services are enabled by default but only reachable via the management tunnel.
