The file `algorithm.doc' within the gzip distribution states that
"If input does not come from a regular disk file, the file
modification time is set to the time at which compression started.".

This has been reported to the `bug-gzip' mailing list (see
http://lists.gnu.org/archive/html/bug-gzip/2010-03/msg00000.html).
In his answer, Eric Blake suggested that the bug might be in
cygwin1.dll.

Regards.
