This is to find the newest files in a directory tree, or the oldest, as the case may be, where newest is defined by 'latest mtime' by default. This can be changed to ctime or atime.
I'd like to thank FreeBSD 4.11's find for not having printf0, which can also do this quite nicely, and which led me to just say I want my own.
newest --help
Usage: ./src/newest [OPTION]... [DIRECTORY]...

By default they are displayed in descending order of last modified time.
-a, --atime sort by access time
-m, --mtime sort by modified time
-c, --ctime sort by inode update time (so-called creation time)
-n, --number=N show the N newest files
-R, --reverse show the oldest files instead
-d, --include-dirs include directories in list instead of only plain files
-q, --quiet suppress timestamp info. show only filenames
-H, --human print timestamp in more friendly format than epoch time
-e, --ignore-empty don't include empty files in the results
-h, --help display this help message and exit
