What potential pitfalls should be considered when sorting data by UNIX timestamps in a PHP query?

When sorting data by UNIX timestamps in a PHP query, one potential pitfall to consider is that the UNIX timestamp is an integer value, so if the data is not sorted correctly, it may be due to the data being treated as integers instead of timestamps. To solve this issue, you can use the `FROM_UNIXTIME()` function in your SQL query to convert the UNIX timestamp to a datetime format before sorting. 

$query = "SELECT * FROM table_name ORDER BY FROM_UNIXTIME(timestamp_column) DESC";
$result = mysqli_query($connection, $query);

if ($result) {
    while ($row = mysqli_fetch_assoc($result)) {
        // Process the sorted data
    }
} else {
    echo "Error: " . mysqli_error($connection);
}
