What NTP source will a Nebula cloud-managed AP use?

The AP uses NTP to synchronize its system clock. In restricted or intranet environments, the AP may be unable to reach the default public NTP servers. For this reason, the AP supports customer-defined NTP settings, including a locally configured NTP server and an NTP server delivered by DHCP Option 42.

In cloud mode, the AP tries NTP sources in the following order:

1. User-defined NTP server configured locally on the AP

2. NTP server received from the DHCP server through DHCP Option 42

3. Nebula-provided NTP server:

0.pool.ntp.org

4. Built-in default NTP servers:

time.google.com

time.cloudflare.com

time.windows.com

time.apple.com

If a higher-priority source is unavailable or synchronization fails, the AP can continue to the next source in the sequence.
