howto update local and fork git repos with latest from upstream

howto amend commit with another date

So you want to add some changes to code, and make it as if your last commit has the changes. Also, you want to keep the date of your last commit. Easy!

1. Do some changes.
2. Make a temporary commit.
3. Rebase interactive, squash last commit.
4. Commit and amend. Set dates by exposing 2 ENV variables GIT_AUTHOR_DATE and GIT_COMMITTER_DATE.
