How can using 'UTC' as the reference time zone help in avoiding time-related discrepancies in PHP code?

Using 'UTC' as the reference time zone helps in avoiding time-related discrepancies in PHP code because it is a standardized time zone that does not observe daylight saving time or any other regional adjustments. By setting the default time zone to 'UTC' in PHP, you ensure that all date and time calculations are consistent and accurate across different servers and locations. 

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

// Now you can perform date and time operations without worrying about discrepancies
$currentDateTime = date('Y-m-d H:i:s');
echo $currentDateTime;
