Is the eight-character fortune-telling based on Beijing time or sun time?

Fortune telling is based on the time of birth, not Beijing time, because there may be time difference. You were born in summer, and you have a strong personality. Last year, you ate a star and got hurt, which was not good for your grandmother's generations, nor for yourself. Because Ma Xing was injured, you moved more and were quiet less. You can add me if you want to calculate the details.
