How can time zone differences affect the accuracy of timestamp calculations in PHP scripts?

Time zone differences can affect the accuracy of timestamp calculations in PHP scripts because timestamps are often stored in UTC time, which may not align with the local time zone of the server or user. To ensure accuracy, it's important to set the correct time zone in your PHP script using the `date_default_timezone_set()` function. This will ensure that all timestamp calculations are done in the correct time zone. 

// Set the default time zone to UTC
date_default_timezone_set('UTC');

// Your PHP script code here
// This will ensure that all timestamp calculations are done in UTC time
