What is c3gHdrSessionStart?

This value reports the starting timestamp, in milliseconds, of the modem's current or most recent HDR (EV-DO) session. An admin uses this alongside c3gHdrSessionEnd to calculate exactly when a session began, useful when correlating cellular connectivity events with other logged incidents. For example, comparing this timestamp against a known outage window can confirm whether the modem's EV-DO session started before or after a reported service disruption.
