This is a clock with special warning significance. Three time periods are marked with four solid points on the clock face, and each time period is 5 minutes. In addition, two movable hands are used on the clock face to mark the time from 1 1: 45 pm to 0: 00 midnight (or 12 pm).

Therefore, the "doomsday clock" of this world is warning us, how long will the world be destroyed? If the "doomsday clock" of the world points to midnight, it means that the nightmare of mankind has begun, when nuclear war will break out and mankind will be wiped out in nuclear war.
