Newer file systems provide Btime (birth time) in addtion to [acm]time, and
while not all OSs support it yet, at least some BSD flavors and cygwin 1.7
do. GNU findutils is able to find files based on Btime, given sufficient
OS and file system support; so although many systems cannot find files
based on creation time, there exist some that can.
