What is the 'stop clock' rule that will be introduced in international cricket?

'Stop clock' rule will be introduced on trial basis in men's ODIs and T20Is from December 2023-April 2024, ICC said. Stop clock will be used to regulate time between overs. If bowling team isn't ready to bowl next over within 60 seconds of previous over being completed, five-run penalty will be imposed the third time it happens in an innings.
