The option --reset-author also resets the date. So 'git commit
--ammend --reset-author' does what 'git commit --amend --date-now'
would do in most cases. I was surpised when I tried 'git commit
--amend --date=now' that git didn't understand 'now' as a date, which
seems like a more obvious place to fix it.
