What are the potential reasons for a PHP server to display time incorrectly?

One potential reason for a PHP server to display time incorrectly is due to incorrect server timezone settings. To solve this issue, you can set the timezone in your PHP script using the `date_default_timezone_set()` function to ensure that the time is displayed correctly.

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

// Display the current date and time in the specified timezone
echo date('Y-m-d H:i:s');
