Git

版本回退

獲取commit hash

git reflog master  //查看本地master分支歷史變更紀錄 | Tower

git reset

git reset --hard <COMMIT_ID>
git reset --hard master@{1} // 回退至當前版本
git push origin master --force // 強行覆蓋遠程記錄

git revert

git revert <COMMIT_ID> // 將該版本(包括該版本)以後的全部修改都回退
git add -A
git commit -am "版本回退"
git push origin master

時間

時間格式轉換
