According to Consumer Affairs, Food & Public Distribution, the Ministry of This initiative, titled aims to ensure uniformity in timekeeping, enhance economic efficiency, and bolster national security.

The project, undertaken in collaboration with the National Physical Laboratory (NPL) and the Indian Space Research Organisation (ISRO), seeks to disseminate IST with millisecond to microsecond accuracy.

To achieve this precision, infrastructure will be established in five Legal Metrology laboratories across India. This effort is expected to significantly benefit sectors such as navigation, telecommunications, power grid synchronization, banking, digital governance, and advanced scientific research, including deep space navigation and gravitational wave detection.

At present, many Telecom Service Providers (TSPs) and Internet Service Providers (ISPs) rely on foreign time sources like GPS instead of IST, posing risks to cybersecurity and the reliability of critical infrastructure. Recognizing these challenges, a high-powered inter-ministerial committee, chaired by the Secretary of Consumer Affairs, has been constituted.  (ANI)
