The timestamp is determined based on the internal timer which has an accuracy of 10ms. Depending on the
configured mechanism (ceiling, floor, round-off) this is translated into the timestamp which only shows the full
seconds.

The format is shown below.
TimeStamp ::= OCTET STRING (SIZE(6))
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

UE Tunnel Information
This field contains the UE Tunnel information (UE IP address and port and ePDG IP address and port on SWu interface). The
IP addresses will be binary encoded and present in sequence. This is an optional proprietary parameter and will be CLI
controlled.
