MySQLの日付関連フォーマット in PHP。多分、他のデータベースでも使えると思うけど、どうなんだろう？
<?php

define('DATE_MySQL_YEAR', 'Y');
define('DATE_MySQL_DATETIME', DATE_MySQL_DATE . ' ' . DATE_MySQL_TIME);
$now = time();
echo date(DATE_ATOM, $now), "\n"; // => 2019-07-19T15:51:27+09:00
echo date(DATE_RSS, $now), "\n"; // => Fri, 19 Jul 2019 15:51:27 +0900
echo date(DATE_MySQL_DATE, $now), "\n"; // => 2019-07-19
