What are the potential pitfalls of passing a timestamp parameter to the strftime method in PHP?

Passing a timestamp parameter to the strftime method in PHP can lead to unexpected results if the timestamp is not in the correct format or timezone. To avoid this issue, it is recommended to convert the timestamp to a DateTime object and set the desired timezone before formatting it with strftime. 

$timestamp = time();
$date = new DateTime();
$date->setTimestamp($timestamp);
$date->setTimezone(new DateTimeZone('UTC'));
$formatted_date = strftime('%Y-%m-%d %H:%M:%S', $date->getTimestamp());
echo $formatted_date;
