Analog clocks have been used for centuries, but the younger generations, due to the abundance of modern technology, find it easier to rely on digital clocks instead.

In the UK, some schools suggested replacing analog clocks with digital versions in examination halls, as some of their students had difficulties to estimate their time remaining from the former. The aim of these changes is to minimize disruptions during standardized examinations, as students are under strict time constraints during these tests. 

This topic came up only in the context of a specific type of exams, and the rest of the classrooms still have analog clocks. The decision was actually ushered in by teachers, who had grown weary of disruptions from students unsure about how much time remained in the testing session.

Malcolm Trobe, the deputy general secretary at the Association of School and College Leaders, explains that the current generations are exposed to time being given digitally everywhere, like on their computers, and cells phones.

Therefore, some of their students struggled to interpret time from analog clocks when they tried to estimate the time they have left during high-stakes standardized examinations.

He emphasized that these students need to be as relaxed as possible during their exams, and such a move would also prevent constant interruptions by students, asking about the remaining time. He also added that there is a big advantage in using digital clocks in exam rooms as students won’t mistake the time when they are working against time.
