Eight-character calculation has great reliability, but it can't decide everything.

It's only dawn before the sun comes out,

Two hours after the sun came out,

Two hours before sunset is the application time.

Two hours after dark,

Two hours is an hour and so on.

It is also Beijing time 10: 58, Qingdao 10: 58 and Lhasa 10: 58.
