No idea why your ctime and mtime disagree - are you sure your system clock and 
BIOS clock match?  Have you recently used an NTP server to align your clock 
with the rest of the world?  However, I want one thing to be clear - ls does 
not list creation time; it lists change time (ctime not stand for creation time 
in POSIX, instead, the BSD notion birthtime, aka Btime, maps to the Windows 
creation time - for full birthtime support in cygwin, you need to use a 
snapshot, as cygwin 1.5.24 does not support querying birthtime).

Also, stat(1) may be nicer than ls(1) for figuring these timestamp issues out.
