How can PHP beginners effectively handle time calculations for industrial purposes?

When handling time calculations for industrial purposes in PHP, beginners can effectively use the built-in DateTime class to perform accurate calculations. This class provides methods for adding, subtracting, and comparing dates and times, making it easier to work with time-related data. 

// Create a DateTime object for the current time
$current_time = new DateTime();

// Add 1 hour to the current time
$current_time->modify('+1 hour');

// Subtract 30 minutes from the current time
$current_time->modify('-30 minutes');

// Compare two DateTime objects
$future_time = new DateTime('2022-01-01 12:00:00');
if ($current_time < $future_time) {
    echo 'Current time is before the future time.';
} else {
    echo 'Current time is after the future time.';
}
