I'm trying to determine when the last time a file in a certain directory was modified. I don't care what file it is, I just want to know when it was last updated. So far I have

ls -aRl --full-time --sort=time
which is close. The problem is that it only sorts within folders, not within the entire directory. How can I determine when the last file was modified?
Hi
I'd like to know if is it possible to find files given a certain modification date (say, 01-05-2006, that's 1st of May 2006)
I can calculate the days backward:
find / -ctime 23
but I wish to search by exact modification day
