Are there any best practices for handling time calculations in PHP to avoid inaccurate results?

When handling time calculations in PHP, it is important to use the proper functions and formats to avoid inaccurate results. One common issue is not accounting for time zones or daylight saving time changes, which can lead to unexpected results. To ensure accurate time calculations, it is recommended to use PHP's built-in DateTime class along with the appropriate methods for adding or subtracting time. 

// Example of handling time calculations using PHP's DateTime class
$date = new DateTime('2022-01-01 12:00:00', new DateTimeZone('UTC'));
$date->modify('+1 day'); // Add 1 day
echo $date->format('Y-m-d H:i:s'); // Output: 2022-01-02 12:00:00
