Yes. The gzip format has a mandatory MTIME field. "If the compressed data did not come from a file, MTIME is set to the time at which compression started. MTIME = 0 means no time stamp is available." (RFC 1952, http://www.gzip.org/zlib/rfc-gzip.html) BTW, it has a 1 second resolution, so if you're fast enough you will get the same output.
