I am not sure if this is what everyone is talking about, but if I have a note I did on the 1st of October in my inbox that I left there for whatever, if I open it on a later date and try to save it, I always get the warning:

This is not today's date. Do you want to print it anyway? I say yes, and it prints on the day of the note, not today's date.

I think it's very slick.
