Nothing can make a person appear more self-centered than being inconsiderate of others time. That is especially true when you are meeting a date. Being on time for a date shows that you respect their time...and that you are excited for the date to begin! If you are chronically late for dates, it can send the message that you don't care about the person, even if that is far from the truth. If you are going to be late, be sure to call your date and let them know...and don't make it a habit.
