In what scenarios should developers consider using UTC as the base time zone for date calculations in PHP?

When working with date and time calculations in PHP, developers should consider using UTC as the base time zone to ensure consistency and avoid issues related to daylight saving time changes or different time zones. By using UTC as the base time zone, developers can perform accurate calculations without worrying about local time zone differences. 

// Set the default timezone to UTC
date_default_timezone_set('UTC');

// Perform date calculations using UTC as the base time zone
$currentTime = time();
$futureTime = $currentTime + (60 * 60 * 24); // Adding 24 hours to the current time
echo "Current UTC time: " . date('Y-m-d H:i:s', $currentTime) . "\n";
echo "Future UTC time: " . date('Y-m-d H:i:s', $futureTime) . "\n";
