Are there any potential pitfalls in using timestamps instead of DATE or DATETIME formats for storing dates in a database?

Using timestamps instead of DATE or DATETIME formats for storing dates in a database can lead to potential pitfalls when performing date-related queries or calculations. Timestamps are stored as integers representing the number of seconds since the Unix epoch, which can make it more difficult to work with date-specific functions in SQL queries. To avoid these issues, it is recommended to use DATE or DATETIME formats for storing dates in the database. 

// Example of using DATE format for storing dates in a MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Inserting a date into the database
$date = "2022-01-01";
$query = "INSERT INTO table_name (date_column) VALUES ('$date')";
$mysqli->query($query);

// Retrieving dates from the database
$query = "SELECT * FROM table_name WHERE date_column = '2022-01-01'";
$result = $mysqli->query($query);
while ($row = $result->fetch_assoc()) {
    echo $row['date_column'];
}
