I’m making a forum post to go along with my issue and pull request.
I have coded the options --stats-one-line-date and --stats-one-line-date-format to extend the usefulness of --stats-one-line.
--stats-one-line-date prepends a default-formatted timestamp with the rsync-style output. This also enables --stats-one-line without requiring that option.

--stats-one-line-date-format - Prepends a user-supplied date string. This also enables --stats-one-line and stats-one-line-date without requiring those options. The date string must be enclosed in quotes and conform to the golang date specs.
