You don't need to put an actual time in that slot. Save the time, get a random number. Put it in the packet and save it too. When a reply arrives, compare the "time stamp" in the packet with the saved random number. If they match, process using the saved time. There was a draft describing that a year or so ago. -- These are my opinions. I hate spam.
