Question: What is the time reference used to calculate the value of the MBMS-Data-Transfer-Start AVP?
Option 1: 00:00:00 on 1 January 1970
Option 2: 00:00:00 on 1 January 1900 (calculated as continuous time without leap seconds and traceable to a common time reference)
Option 3: The current system time of the User Equipment (UE)
Option 4: The time when the MBMS session was established
Explanation: According to the specification, the value of the MBMS-Data-Transfer-Start AVP is calculated relative to 00:00:00 on 1 January 1900, taking into account continuous time without leap seconds and traceable to a common time reference. This ensures that all nodes in the network have a consistent understanding of the timing for radio resource setup.
