What potential pitfalls should be considered when implementing PHP code to sort MySQL tables based on time-sensitive criteria?

When implementing PHP code to sort MySQL tables based on time-sensitive criteria, it is important to consider potential pitfalls such as time zone differences, server time settings, and the format of the timestamp data in the database. To ensure accurate sorting based on time, it is recommended to store timestamps in a standardized format (such as UNIX timestamp) and to handle time zone conversions appropriately in the PHP code. 

// Example PHP code snippet to sort MySQL table based on time-sensitive criteria

// Set the default time zone to UTC
date_default_timezone_set('UTC');

// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Query to select data from table and sort by timestamp in descending order
$query = "SELECT * FROM table_name ORDER BY timestamp_column DESC";
$result = $mysqli->query($query);

// Fetch and display the sorted data
while ($row = $result->fetch_assoc()) {
    echo $row['id'] . " - " . $row['data'] . " - " . date('Y-m-d H:i:s', $row['timestamp_column']) . "<br>";
}

// Close the database connection
$mysqli->close();
