What best practices should be followed when working with date and time calculations in PHP to ensure accuracy and consistency?

When working with date and time calculations in PHP, it is important to set the correct timezone, use the appropriate date and time functions, and handle daylight saving time changes properly to ensure accuracy and consistency. 

// Set the timezone
date_default_timezone_set('America/New_York');

// Get the current date and time
$currentDateTime = new DateTime();

// Perform date and time calculations
$newDateTime = $currentDateTime->modify('+1 day');

// Display the result
echo $newDateTime->format('Y-m-d H:i:s');
