What are potential pitfalls when using strtotime in PHP to manipulate dates?

Using strtotime in PHP to manipulate dates can lead to potential pitfalls, such as unexpected results when parsing ambiguous date formats or incorrect handling of timezones. To mitigate these issues, it's recommended to provide strtotime with unambiguous date formats and explicitly set the timezone when working with date and time functions in PHP. 

// Example of using strtotime with an unambiguous date format and setting the timezone explicitly
$dateString = '2022-01-15';
$timestamp = strtotime($dateString);
$date = new DateTime();
$date->setTimestamp($timestamp);
$date->setTimezone(new DateTimeZone('UTC'));
echo $date->format('Y-m-d H:i:s');
