Just a quick note sharing something I learnt recently.��
When migrating MCZ repos to git, set the commit-date of the first empty commit back past the first MCZ��date.
After the MCZs have been exported, check the commit-date matches the author date.
$ git log --format=fuller����
or otherwise force it so...
$��git filter-branch --env-filter 'export GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"'
