Are there best practices for handling dates and times in PHP to avoid incorrect conversions?

When handling dates and times in PHP, it's important to set the correct timezone to avoid incorrect conversions. One best practice is to always use the DateTime class along with the setTimezone() method to ensure consistent handling of dates and times.

// Set the default timezone to UTC
date_default_timezone_set('UTC');

// Create a new DateTime object with the current date and time
$now = new DateTime();

// Set the timezone to the desired timezone
$now->setTimezone(new DateTimeZone('America/New_York'));

// Output the current date and time in the desired timezone
echo $now->format('Y-m-d H:i:s');
