How can the PHP code provided be optimized or improved for better performance when including date and time in a form?

When including date and time in a form, it is important to optimize the PHP code to improve performance. One way to do this is by reducing unnecessary calculations or function calls. One approach is to use client-side scripting like JavaScript to handle date and time inputs before submitting the form to the server. This can reduce the workload on the server and improve the overall performance of the form. 

// Example of using JavaScript to handle date and time inputs before submitting the form

<!DOCTYPE html>
<html>
<head>
    <title>Date and Time Form</title>
    <script>
        function validateForm() {
            // Get the date and time values from the form
            var date = document.getElementById('date').value;
            var time = document.getElementById('time').value;

            // Perform any necessary validation or manipulation here

            // Set the formatted date and time values back to the form fields
            document.getElementById('date').value = date;
            document.getElementById('time').value = time;

            // Submit the form
            document.getElementById('myForm').submit();
        }
    </script>
</head>
<body>
    <form id="myForm" action="process.php" method="post">
        <label for="date">Date:</label>
        <input type="date" id="date" name="date"><br><br>
        
        <label for="time">Time:</label>
        <input type="time" id="time" name="time"><br><br>

        <input type="button" value="Submit" onclick="validateForm()">
    </form>
</body>
</html>
