What are the implications of storing date/time values in UTC format in MySQL?

Storing date/time values in UTC format in MySQL ensures consistency across different time zones and simplifies date/time calculations. To display the date/time values in a user's local time zone, you can convert them to the user's time zone in your application code. 

// Retrieve date/time value from MySQL in UTC format
$utcDateTime = '2022-01-01 12:00:00';

// Convert UTC date/time to user's time zone (e.g., 'America/New_York')
$userTimeZone = new DateTimeZone('America/New_York');
$utcDateTimeObject = new DateTime($utcDateTime, new DateTimeZone('UTC'));
$utcDateTimeObject->setTimezone($userTimeZone);

// Display the date/time in the user's time zone
echo $utcDateTimeObject->format('Y-m-d H:i:s');
