I'm getting ready for my AW inspection. Yay.

In the log book, there is space for some assertions that have a blank with (insert mfr date here).

Is the manufacture date one I just pull out of thin air? The date of the inspection? The date of last builder log entry? Something else?

Also, is it any concern if I have my Class B mode "C" transponder cert log entry before any other entry or completion assertion by me?

Thanks!
