System: FreeBSD melamine.cuivre.fr.eu.org 8.0-STABLE FreeBSD 8.0-STABLE #0: Sun Mar 28 14:46:11 CEST 2010 thomas@melamine.cuivre.fr.eu.org:/usr/obj/usr/src/sys/GENERIC amd64
>Description:
When a file name is provided on the command line, gzip -c does not
save its timestamp in the output compressed stream.
>How-To-Repeat:
cd /tmp
touch foo
gzip -c foo > foo1.gz
gzip foo
file foo1.gz foo.gz
foo1.gz: gzip compressed data, was "foo", from Unix
foo.gz: gzip compressed data, was "foo", from Unix, last modified: Tue Jun 1 11:55:30 2010
