With reference to the ‘One Nation, One Time’

Solution

• Statement 1 is correct – The initiative mandates IST as the single standard across all legal, commercial, digital, and administrative domains. • Statement 2 is NOT correct – India will not rely on foreign satellite systems anymore; instead, it will use NavIC and the National Physical Laboratory (NPL) for timekeeping. • Statement 3 is correct – Atomic clocks at five locations will provide nanosecond-level accuracy, limiting discrepancies to less than 0.1 milliseconds. • Statement 4 is correct – The move directly benefits telecom, defense, banking, power grids, and stock exchanges, all of which require precise synchronization. Additional Context: • Announced by Union Minister Pralhad Joshi at a roundtable in Delhi. • Implementation begins phased from Q1 FY26. • Strengthens India’s self-reliance in timekeeping and reduces dependency on foreign satellite systems. • Critical for efficiency, cybersecurity, and national security.
