How to set the time source on devices running the DAL Operating System.

The DAL Operating System offers several options to configure a time source:

• An NTP client, using one or more NTP servers as its time source.
• The device's cellular modem.
• GNSS (if the device has a GNSS module).

To configure the time source from the device's webUI, navigate to Device Configuration > System > Time > Time sources. 

Multiple time sources may be added by clicking the plus sign next to 'Add Source'.  The device's system time will be synchronized to the first source in the list that returns valid time information.

The following screenshot shows a device with tree time sources, the first being NTP, the second being the device's cell modem, and the third being the device's GNSS module.
