<?php
function getRandomDateTime($startDate, $endDate) {
    $startTimestamp = strtotime($startDate);
    $endTimestamp = strtotime($endDate);
    if ($startTimestamp > $endTimestamp) {
        throw new Exception("Start date must be before end date");
    }
    $randomTimestamp = mt_rand($startTimestamp, $endTimestamp);
    return date('Y-m-d H:i:s', $randomTimestamp);

$startDate = '2020-01-01 00:00:00';
$endDate = '2023-12-31 23:59:59';
$randomDateTime = getRandomDateTime($startDate, $endDate);
