your birth time is not accurate.
its needs adjustment by few minutes.
if born at exactly 4:30 pm, you should get married to same guy whom you loved, though delayed.
also your partner will be 8-10 yrs or even more older than you.
so, if you can tell few more important events of life like, college graduation year(date), when you left your country, when you met him, his birth info or atleast your parents birth info, it will help to derive correct time
