Schools in the U.K. are removing analog clocks from exam rooms after students complained about not being able to read the time, according to The Telegraph.

Malcom Trobe, deputy general secretary at the Association of School and College Leaders, says students are accustomed to using digital devices today.

"They are used to seeing a digital representation of time on their phone, on their computer," Trobe told The Telegraph. "Nearly everything they've got is digital so youngsters are just exposed to time being given digitally everywhere."

Teachers are concerned about students stressing out during exams because they can't keep track of time. One educator said her high schoolers are only able to tell the time on devices with digital displays, which they can't use during exams, according to People.

Many teachers turned to Twitter to share their experience and found that issues with analog clocks is a common trend.

Apparently many Y9, 10 and 11 cannot tell the time with an analogue clock. 😳

Some schools have already replaced all analog clocks with digital in examination rooms. But it's not just a European problem -- a 2017 study showed 4 in 5 Oklahoma City kids couldn't read analog clocks either, according to KFOR.
