I understand your argument, and offer the following, which is from the same section of the python docs: "On other Unix systems (such as FreeBSD), the following attributes may be available (but may be only filled out if root tries to use them): * |st_birthtime| - time of file creation" Suggesting that it's not "anti-POSIX" (unPOSIX? aPOSIX?) to provide the information if it's available. Anyway, I've found a more or less suitable workaround for now, batching up the queries and calling out to the shell - so I'll leave it at that. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
