What are the benefits of using the "!" format specifier in the DateTime class for handling date calculations in PHP?

When working with date calculations in PHP, using the "!" format specifier in the DateTime class can be beneficial because it represents the Unix timestamp format, which is a standardized way of representing dates and times as a single number. This can make it easier to perform calculations, comparisons, and conversions with dates. 

// Example of using the "!" format specifier in DateTime class for date calculations
$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-01-10');

// Calculate the difference in seconds between two dates using the Unix timestamp format
$diffInSeconds = $date2->format('U') - $date1->format('U');

echo "The difference in seconds between the two dates is: $diffInSeconds seconds.";
