[LU Chuck] I find the git filter-branch can't recognize commits range commitA..commitB,
         it can only recognize branchA..branchB. (branchA point to commitA, branchB point to commitB.)
         And you are right, I need remove the useless ... .
         
         So I fixed the previous command as following:
         Create a new branch temp2 point to 67d9d9 and switch to temp branch(point to f70bf4), then it works.
         git filter-branch --env-filter 'export GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"' temp2..temp

         By the way, who can improve the documentation on https://git-scm.com/docs/git-filter-branch? Currently the demo using git filter-branch with commits range commitA..commitB.
         Or anyone can make it possible to support the commit range by commitA..commitB?
