What are the advantages and disadvantages of using DateTime objects in PHP for tracking building upgrade times in a browser game?

Issue: When tracking building upgrade times in a browser game, using DateTime objects in PHP can provide accurate time calculations and easy manipulation of dates. However, DateTime objects can be resource-intensive and may not be suitable for high-traffic games with many concurrent users. 

// Example of using DateTime objects to track building upgrade times in a browser game

// Set the current upgrade time for a building
$upgradeTime = new DateTime();
$upgradeTime->add(new DateInterval('PT1H')); // Upgrade time set to 1 hour from now

// Check if the building upgrade is completed
if (new DateTime() >= $upgradeTime) {
    echo "Building upgrade is completed!";
} else {
    $timeLeft = $upgradeTime->diff(new DateTime());
    echo "Building upgrade will be completed in " . $timeLeft->format('%H hours, %i minutes, %s seconds');
}
