Record Opening Time
This field contains the time stamp when PDP context is activated in PDG or when a subsequent record is opened after a
partial record.
partial record.
The timestamp is determined based on the internal timer which has an accuracy of 10ms. Depending on the configured
mechanism (ceiling, floor, or round-off) this field is translated to only show full seconds.

The contents of this field are a compact form of the UTC Time format containing local time plus an offset to universal
time. Binary coded decimal encoding is employed for the digits to reduce the storage and transmission overhead

Record Sequence Number
A running sequence number with the range of 1 through 4294967295 used to link partial records generated by the PDG
for a specific PDP context (characterized with the same Charging ID and PDG address pair). This field is not present if
the first record is also the final record.
