THE Centre has announced a significant move toward achieving precision and uniformity in timekeeping across the country. The Draft Legal Metrology (Indian Standard Time) Rules, 2025, published for public consultation on January 15, are aimed at standardising and mandating the use of Indian Standard Time (IST) across all sectors in India. The initiative is being developed in collaboration with the National Physical Laboratory (NPL) and the Indian Space Research Organisation (ISRO), with the goal of disseminating IST with millisecond to microsecond accuracy.
The new rules are expected to transform several critical sectors such as telecommunications, navigation, power grid synchronization, banking, and digital governance, where precision timing is essential.
Additionally, the project is anticipated to significantly impact scientific research, including deep space navigation and gravitational wave detection. Despite its importance, the adoption of IST has not been mandatory for all Telecom Service Providers (TSPs) and Internet Service Providers (ISPs), many of whom rely on foreign time sources, such as GPS, for synchronisation. The new rules aim to close this gap by ensuring the widespread adoption of IST, thus facilitating seamless operation of critical infrastructure nationwide.
The Legal Metrology (Indian Standard Time) Rules, 2025 will establish a robust regulatory framework for the adoption of IST, encompassing synchronisation, time-stamping, and cybersecurity protocols. The rules will require all Government offices, public institutions, and private sector entities to synchronise their operations with IST, utilising established protocols such as Network Time Protocol (NTP) and Precision Time Protocol (PTP). The rules also provide exceptions for scientific, astronomical, and navigational purposes, but these will require prior government approval. Penalties will be imposed for violations, and regular audits will be conducted to ensure compliance.
