How can PHP developers improve efficiency and accuracy when calculating time differences between a future date and the current time?

When calculating time differences between a future date and the current time in PHP, developers can improve efficiency and accuracy by using the DateTime class. This class provides methods for easily calculating time intervals and differences, as well as handling timezones correctly. 

$currentDate = new DateTime();
$futureDate = new DateTime('2023-01-01');
$timeDifference = $currentDate->diff($futureDate);

echo $timeDifference->format('%y years, %m months, %d days, %h hours, %i minutes, %s seconds');
