In what ways can PHP scripts be optimized for accurate date comparisons and calculations?

When working with date comparisons and calculations in PHP, it's important to ensure that the timezone settings are correctly configured to avoid any discrepancies. One way to optimize PHP scripts for accurate date comparisons and calculations is to explicitly set the timezone using the `date_default_timezone_set()` function to ensure consistency across different servers. 

// Set the timezone to UTC for accurate date comparisons and calculations
date_default_timezone_set('UTC');

// Now you can perform date comparisons and calculations with confidence
$today = date('Y-m-d');
$nextWeek = date('Y-m-d', strtotime('+1 week'));
