What are some best practices for handling time-related calculations in PHP, considering different versions and potential limitations?

When handling time-related calculations in PHP, it's important to consider different PHP versions and potential limitations that may arise. One best practice is to use the DateTime class, introduced in PHP 5.2, for accurate date and time manipulations. This class provides a more object-oriented approach to working with dates and times, ensuring consistency across different PHP versions. 

// Example of using DateTime class for time-related calculations
$date = new DateTime('2022-01-01');
$date->modify('+1 day');
echo $date->format('Y-m-d');
