What potential pitfalls should be considered when extracting specific time values from a datetime string in PHP?

When extracting specific time values from a datetime string in PHP, potential pitfalls to consider include ensuring that the datetime string is in a format that can be parsed correctly, handling timezones correctly, and accounting for daylight saving time changes. It's important to use the appropriate PHP functions, such as strtotime() or DateTime::createFromFormat(), to parse the datetime string and extract the desired time values accurately. 

// Example code snippet to extract specific time values from a datetime string
$datetimeString = '2022-01-15 14:30:45';
$dateTime = new DateTime($datetimeString);
$hour = $dateTime->format('H');
$minute = $dateTime->format('i');
$second = $dateTime->format('s');

echo "Hour: $hour, Minute: $minute, Second: $second";
