Specifically, looking at tar(1) from -head, I see that it doesn't current support the -mtime flag that GNU tar does, to be able to set the timestamp on all of the files being archived. Any thoughts on what the canonical way will be: e.g. a pass in advance with find/touch or if BSD tar is planned to support this internally? Thanks! Derek
