The International Bureau of Weights and Measures (BIPM) moved the end of leap seconds forward from 2035 to 20 May 2027. UTC will no longer be adjusted, and it will be locked to TAI with a fixed offset. The reason is that the Earth has been spinning faster, so a negative leap second might have been needed. Removing one for the first time was seen as risky for financial and IoT systems. For most small businesses this changes nothing day to day. If you use POS, accounting, or connected devices that sync time, your software vendor should confirm it handles the new standard.
