What potential pitfalls should be considered when implementing time-based image switching in PHP?

One potential pitfall to consider when implementing time-based image switching in PHP is ensuring that the time zone is correctly set to avoid discrepancies in image switching based on different server time zones. To solve this issue, you can explicitly set the time zone in your PHP script using the `date_default_timezone_set()` function. 

// Set the time zone to avoid discrepancies
date_default_timezone_set('America/New_York');

// Your image switching logic here
