What are the potential challenges of handling time zones in PHP, especially in regions like Mongolia with multiple time zones?

Handling time zones in PHP can be challenging, especially in regions like Mongolia with multiple time zones. One way to address this is by using the DateTimeZone class to accurately handle different time zones. By setting the appropriate time zone for each region, you can ensure that date and time calculations are accurate regardless of the region's time zone differences. 

// Set the default time zone to UTC
date_default_timezone_set('UTC');

// Create a DateTime object for Mongolia time zone
$mongoliaTime = new DateTime('now', new DateTimeZone('Asia/Ulaanbaatar'));

// Format the date and time for Mongolia
echo $mongoliaTime->format('Y-m-d H:i:s');
