Might ''after'' have the same meaning as ''past''
While I was watching a movie, I have come across this line from a character:
''No more typing now, Miss Ashton. It's well after ten''.
I realize that ''after'' is used to mean that it is some minutes past ten (for instance, it could be 10:40 p.m.). So, what I really want to know is whether I can substitute ''after'' for ''past'' (and whether the sentence would still have the same meaning)?!
Thank you in advance.
