Are there any specific PHP libraries or resources that can assist in time calculations and conversions?

When working with time calculations and conversions in PHP, the DateTime class can be very helpful. This class provides various methods for manipulating dates and times, including adding or subtracting intervals, formatting dates, and converting between timezones. By using the DateTime class, you can easily perform time-related operations in PHP.

// Create a DateTime object with the current date and time
$now = new DateTime();

// Add 1 day to the current date
$now->modify('+1 day');

// Format the date in a specific format
$formattedDate = $now->format('Y-m-d H:i:s');

echo $formattedDate;
