Tell me. Does Wei Zi's horoscope look at Beijing time or sundial, that is, local time?

According to my own practice for many years, the figures of four pillars and eight characters and Wei Zidou should be based on the conversion of time between the apparent solar time (sundial and local time): Beijing clock time->; Local average solar time-> It is more accurate to look at the sun. There must be a lot of inaccuracies in looking at Beijing time, and we have to consider daylight saving time.

For example, if a person was born in Hangzhou, Zhejiang at 9: 10 on June 3, 987 (Year of the Rabbit) (the second time according to Beijing time), the date of birth is: Ding Mao, Shen.
