check commit timestamp & hash

How?

1. change commit timestamp using git filter-repo.

   git filter-repo --commit-callback '
       # UNIX time. Not using 0 because it might cause bug.
       commit.author_date = b"1 +0000"
       commit.committer_date = b"1 +0000"
   
       from pprint import pprint
       pprint(commit.__dict__)
       print("----")
   ' --refs master --force
   

2. Change hash using lucky-commit.
