Are there any potential pitfalls to be aware of when deleting entries based on time in PHP?

When deleting entries based on time in PHP, one potential pitfall to be aware of is not properly handling timezones. If your server's timezone is different from the timezone of the entries you are deleting, it could lead to inaccuracies in the deletion process. To solve this issue, always make sure to set the correct timezone before performing any time-related operations in your PHP script. 

// Set the timezone to the timezone of the entries
date_default_timezone_set('America/New_York');

// Your code to delete entries based on time
// For example, deleting entries older than 7 days
$sevenDaysAgo = strtotime('-7 days');
// Perform deletion query using $sevenDaysAgo
