    First off, don't check user credentials like that.
    SELECT username FROM admin WHERE username = ? AND password = ?
    Then use a PreparedStatement and bind (use setString()) to set the two variables.
    Then you either get one row back ( is true) in which case these are correct, or no rows, in which case they are wrong.

    As for your actual problem, is there a table in your database for storing the login time?
    Then insert a row.
    If it's just a last_logged_in column in the admin table then just UPDATE that value with the current time stamp.
    Please do not ask for code as refusal often offends.
