gzip doesn't do this.  It also doesn't normally recognize this kind of
name as a gzip archive.  There's nothing to stop you writing a
wrapper, though, like:

#!/bin/sh
for i in $*; do
  gzip $i
  mv $i.gz $i.`date "+%d%m%y"`.gz
done

This will rename the file in your example to cache.log.050598.gz.
