【純手工打造】時間戳轉換工具（python）

1.背景

最近發現一個事情，如果日誌中的時間戳，需要我們轉換成時間，增加可讀性。或者將時間轉換成時間戳，來配置時間。相信大多人和我一樣，都是開啟網頁，搜尋線上時間戳轉換工具，然後複製貼上進去。個人認為可以手工打造一個python版本的時間戳轉換工具，來解放雙手，減少開啟網頁的時間，於是乎就產生了自己做個小工具的想法。

2.實際效果

廢話不多說，直接上做出來的工具截圖

是的，你沒看錯，這工具是有視覺化介面的，而且是exe單檔案，window上可以直接執行，而且擁有多個複製按鈕，方便我們操作

3.實現原理

借用python的tmath庫、datetime庫輕鬆搞定，然後藉助tkinter實現視覺化介面，借用pyinstaller命令，將python專案一鍵構建exe單檔案。這些庫都可以用pip安裝，不再贅述。

4.原始碼
