Does Cygwin have a "stat" command? This can be used to return only the
information you want about a file.

For example:

serene:conrads:/bin$ stat -f "%Sa %8z %N" *
Jan 26 06:43:14 2006 11304 [
Jan 27 23:30:00 2006 11208 cat
Jan 27 12:32:08 2006 7304 chflags
Jan 25 10:19:53 2006 17128 chio
(output truncated)

This, in combination with find/xargs, should do the trick nicely, I would
think.
