AI can’t generate correct analog clocks to tell time, and here’s why

AI gets the correct time less than one out of four times

Artificial intelligence can fulfill several requests except generating and drawing the correct analog clocks to tell time. It seems strange since clocks are everywhere, and they look simple to produce even digitally. AI systems have also seen millions of clock pictures and read lots of explanations about how clocks work using their own language models, but still, when scientists test AI to produce images and working correct analog clocks, the results are poor.

In many tests, AI gets the correct time less than one out of four times. Based on the studies, a common mistake when scientists use AI to generate the correct analog clocks is mixing up the hour hand and the minute hand. Sometimes the system imagines hands that are not really there, hence creating awry-looking and displaced hands. They also tend to show the time as 10:10, even when that is clearly wrong. This happens because many clocks in ads and photos are set to 10:10, so the AI learns to copy that pattern instead of actually reading the clock.

Why can’t AI generate the correct analog clocks?

The main problem why AI can’t generate the correct analog clocks is that it doesn’t truly see clocks the way people do. When a person looks at a clock, they understand that the hands move in circles and that their positions are connected to time passing. AI does not understand this movement or the idea of time in a physical sense. It only recognizes patterns from pictures and words it has seen before. Some studies have noted that the software also understands clocks through language, not real experience. It has read sentences like ‘the minute hand points to 12,’ but it does not understand angles, rotation, or how gears work inside a clock. 

So when it tries to create or read a clock, it guesses based on what looks familiar, not on how a clock works. This is why AI often draws clocks with numbers in the wrong places or letters that look like messy symbols instead of real numbers, as shown in this project by Brian Moore, inspired by the idea of the programmer Matthew Rayfield. On the site, the creative director displays clocks that have been generated by nine different AI models, which change every minute. These generated time-telling tools can prove that AI can’t always produce the correct analog clocks, just accurate-looking ones, and even so, they come out quite rarely and downgrade again after a minute.

AI is good at copying, not understanding

Another big reason for these mistakes is that AI does not have a ‘world model,’ meaning it cannot imagine how things change over time. It cannot think, ‘if one minute passes, the minute hand moves a little.’ Instead, it treats each image as a still picture. Because of this, it sometimes creates clocks that could never exist in real life. Researchers see this clock problem as an important lesson. 

It shows that AI is good at copying appearances but not at understanding how things function. Some scientists are trying to fix this by teaching AI rules, using math or code to draw clocks correctly, or giving it guides that show where the hands and numbers should go. For now, producing correct analog clocks remains a tough challenge for AI, a reminder that just because a machine can recognize a pattern doesn’t mean it can truly understand it.

  • Blackened Wood Apartment

    Taiwanese architecture studio CTT Architects designed this interior project for a doctor in Taipei City. The apartment is located on the 21st floor of the residential tower nestled in the mountains surrounding the Taipei Basin. The design concept places emphasis on the connection to the surrounding vistas. In contrast with the original layout, the living area has been rearranged such that one can enjoy the amazing urban night views whilst introducing the external greenery inside during the day. We have also tailored the layout to meet the requirements of the client’s modern life. Following a busy day at work, he can completely unwind in the living room in the midst of the mesmerising urban night views; and be awoken by the dappled morning sunlight reflecting off the surrounding green mountains. We believed that every aspect of an interior design requires a bespoke response to its own contextual surrounding as well as to the individual needs of the occupants. The different spatial functions such as bedroom and bathroom are seen as different grey units in the public space. However, homely styling is found inside the master bedroom. Wooden finishings are used to complement subtle light grey walls allowing the stunning views to be the main element – lush green mountain landscapes. At the entrance to the apartment, the simple grey wall with a small bench gives an air of simplicity in complete contrast with the mountain views seen through the expanse of the three window units, which speak for themselves. In the kitchen and dining area, the open plan provides ample space that can be adapted flexibly to suit the changing needs of the modern city dweller. In terms of material selection, fine textured black charred timber panels are deliberately chosen to frame the surrounding mountain and city views. The design strategy is to use the black charred wall to contrast with the green and sky during the day; at night, the blackened panels blend seamlessly into the night view. The custom-made black island comes with black taps to contrast with the white kitchen joinery behind. When it comes to detailing, our approach is to delineate different architectural elements through shadow gaps. For example the walls and ceilings are detached using shadows gaps which are also accentuated by indirect lighting after sunset. Every architectural element has been detached including the ceiling, beams, and walls to showcase themselves as individual elements and avoiding detractive decorations.
