What are some best practices for handling time intervals and scheduling constraints in PHP applications?

When working with time intervals and scheduling constraints in PHP applications, it is important to use the DateTime class for accurate date and time calculations. Additionally, utilizing functions like date_diff() can help calculate the difference between two dates or times. It's also recommended to handle time zones appropriately to avoid any discrepancies in scheduling. 

// Example code snippet for calculating the difference between two dates
$startDate = new DateTime('2022-01-01');
$endDate = new DateTime('2022-01-15');
$interval = $startDate->diff($endDate);
echo $interval->format('%R%a days');
