UTC Time

These instructions will explain how to associate Surveyor data points with accurate UTC time.

If you are running running the Surveyor while connected to SonarLink, here is the easiest method for getting accurate time.

If your application does not support running SonarLink with the Surveyor, you can configure the Surveyor to use a specific NTP server for accurate UTC time. To do this, ensure you have access to an NTP server and send a SET_NET_INFO ping packet to the Surveyor.

• If the Surveyor and the NTP server are on the same subnet, you can set both subnet_mask and gateway_ip to 0.

• If the NTP server is on a different subnet and requires routing through a gateway, you must specify the appropriate subnet_mask and gateway_ip.

In both cases, the Surveyor will automatically synchronize its time using either SonarLink or the designated NTP server, ensuring all data is accurately timestamped with UTC time.
