It's not obvious that the time that a file existed is not meant.
Creation time is what came to my mind, and I find the actual meaning a
bit surprising.  Maybe I even didn't use this function where I should
have and reinvented the thing because of a wrong expectation.  So a +1
from me for trying to make it clearer.

I know already saving files may create a new file and rename the
existing one to a backup name - or keep the file etc.  But anyway, let's
at least say that creation time is not meant, but most of the time, last
file modification.


Michael.
