Mifare Snoop Data APDU Commands or Value ?? Challenge Response ??

It is an apdu command that sniffs the write process of Mifare Plus (hf 14a snoop).

We are using this part to write information on the card.

I do not know what this command or value is.

I think of it as a timestamp.

Attach the following figure and the collected apdu command.

apdu
