Is there a difference between eight-character fortune telling and two-minute difference?

Is there a difference of 2 minutes?

Answer: ① Sometimes there is no difference. For example: 04: 00: Yin Shi, two minutes short, 03: 58, or Yin Shi, 04: 02, still.

It's Yin Shi.

(2) Sometimes there are differences. For example: 05: 00 (Shi Mao), two minutes to 04: 58 (Yin Shi). This is the difference.
