This read-only TODOutputFormat object reports which time-of-day output format the port is using, determining how the time value is encoded on the wire. This matters because the receiving equipment, such as a base station timing input, must be configured to expect the exact same format or it cannot parse the time. For example, if a connected radio unit expects an NMEA-style time string, this object would need to reflect that same output format for the link to work.
