What best practices should be followed when formatting and displaying time differences in PHP functions?

When formatting and displaying time differences in PHP functions, it is important to consider the timezone settings to ensure accurate results. It is recommended to use the DateTime class along with the DateTimeZone class to handle time zone conversions and calculations. Additionally, formatting the output using the date() function with appropriate parameters will help display the time difference in a clear and understandable way. 

// Example code to format and display time differences in PHP

// Set the timezones
$timezone1 = new DateTimeZone('America/New_York');
$timezone2 = new DateTimeZone('Asia/Tokyo');

// Create DateTime objects with different timezones
$date1 = new DateTime('2022-01-01 12:00:00', $timezone1);
$date2 = new DateTime('2022-01-01 12:00:00', $timezone2);

// Calculate the time difference
$interval = $date1->diff($date2);

// Format and display the time difference
echo $interval->format('%R%a days %H hours %I minutes');
