Centre notifies rules mandating IST as common time reference; 180-day window for compliance

The Indian government has mandated the use of Indian Standard Time (IST) as a common time reference for all legal, administrative, commercial, and official purposes across the country. The Legal Metrology (Indian Standard Time) Rules, 2026, were notified by the consumer affairs ministry on August 27 and will take effect 180 days after publication in the official gazette.

The move aims to address the growing reliance on digital and technology-based systems, which require accurate and synchronised time stamps. According to The Economic Times, these systems include banking and payments, telecommunications, railways, power grids, and computer networks.

A uniform national time standard is expected to ensure accurate time-stamping of transactions, improve coordination across transport systems, and support the reliable functioning of telecommunications and internet networks. The Hindu notes that the current use of different time sources can create inconsistencies that may affect coordination and recording of activities.
