What steps can be taken to troubleshoot and resolve PHP time-related issues when var_dump(time()) results in unexpected timestamps?

When `var_dump(time())` results in unexpected timestamps, it could be due to the server's timezone settings not being configured correctly. To troubleshoot and resolve this issue, you can set the timezone explicitly in your PHP script using the `date_default_timezone_set()` function.

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

// Now var_dump(time()) should display the correct timestamp based on the specified timezone
var_dump(time());
