What are some common mistakes that developers make when working with timestamps in PHP and MySQL?

One common mistake when working with timestamps in PHP and MySQL is not properly handling timezones. It's important to set the correct timezone for both PHP and MySQL to ensure consistency in timestamp values across different systems. To solve this issue, you can set the timezone using the date_default_timezone_set function in PHP and the SET time_zone command in MySQL. 

// Set the timezone for PHP
date_default_timezone_set('America/New_York');

// Set the timezone for MySQL
$mysqli = new mysqli("localhost", "username", "password", "database");
$mysqli->query("SET time_zone = 'America/New_York'");
