What are the differences between using Date() in JavaScript and PHP for time calculations?

When using Date() in JavaScript for time calculations, keep in mind that JavaScript operates on the client-side, using the user's local system time. On the other hand, PHP operates on the server-side, using the server's system time. This can lead to discrepancies in time calculations if the client and server are in different time zones. To ensure consistency, consider using server-side time calculations in PHP for critical operations. 

// Get the current server-side time in PHP
$current_time = time();

// Perform time calculations as needed
$new_time = $current_time + 3600; // Add an hour to the current time

// Output the new time
echo date("Y-m-d H:i:s", $new_time);
