The central government has issued a directive establishing Indian Standard Time (IST) as the sole official timekeeper for all legal, administrative and official purposes across India. The mandate eliminates the use of alternative time references in government functions and ensures uniformity in timekeeping protocols.

The decision underscores the government's commitment to administrative standardization and operational efficiency. By designating IST as the singular temporal authority for official use, the Centre seeks to eliminate potential inconsistencies that may arise from multiple time references in legal proceedings, document filing and government transactions.

IST, which is UTC+5:30, has long served as India's standard time across all states and union territories. The formal mandate reinforces its universal application in official contexts, streamlining compliance requirements for government departments, judicial bodies and administrative agencies.

The directive is expected to facilitate smoother inter-departmental coordination and enhance clarity in time-sensitive administrative matters. Government departments and agencies have been advised to ensure strict adherence to the new timekeeping standard across all official documentation and proceedings.
