What are the advantages of using DateTime functions in PHP for time calculations, especially when dealing with milliseconds?

When dealing with time calculations, especially when working with milliseconds, using DateTime functions in PHP can provide several advantages. DateTime functions offer built-in methods for handling date and time calculations, making it easier to perform operations such as adding or subtracting milliseconds from a given timestamp. Additionally, DateTime functions handle time zone conversions and daylight saving time adjustments automatically, ensuring accurate results across different time zones. 

// Create a DateTime object with milliseconds
$date = DateTime::createFromFormat('U.u', microtime(true));

// Add 500 milliseconds to the current timestamp
$date->modify('+0.5 seconds');

// Format the updated timestamp with milliseconds
echo $date->format('Y-m-d H:i:s.u');
