Time is working out for the bounce 2d. In 2022, metrologists voted to desert the timekeeping quirk via 2035. In contrast to the intercalary year, which happens each and every 4 years, the bounce 2d is deployed every time clocks want adjusting because of diversifications in Earth’s spin inflicting slight adjustments within the duration of an afternoon. International officers have inserted a bounce 2d 27 instances since 1972. However satellites and different tech that depend at the actual time stored via atomic clocks can glitch when the clocks are adjusted (SN: 4/22/06, p. 248). Scientists have urged the use of a bounce minute as a substitute, which will require atomic clocks be reset as soon as each and every 50 years or so.
