Are there any specific PHP functions or libraries that can be utilized to simplify time calculations and display in this scenario?

To simplify time calculations and display in PHP, you can utilize the DateTime class along with its methods to easily manipulate and format dates and times. This class provides a wide range of functionalities for working with dates and times, making it a convenient choice for time-related operations in PHP.

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

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

// Format the time in a specific way
$formatted_time = $current_time->format('Y-m-d H:i:s');

echo "Current time + 1 hour: " . $formatted_time;
