Why in News

  • The Union Minister for Consumer Affairs, Food & Public Distribution launched a timing network based on **White Rabbit Technology** at **RRSL Bengaluru**.
  • This network distributes **Indian Standard Time (IST)** across critical digital systems to establish secure national **Digital Public Infrastructure (DPI)**.

What is the IST Dissemination Demonstration Network?

  • The **IST Dissemination Demonstration Network** is a secure, tamper-resistant system that distributes precise national time across digital infrastructure.
  • Three major organizations created this network jointly: the **Department of Consumer Affairs**, **CSIR-NPL**, and **ISRO**.
  • It delivers time signals linked to national standard **UTC (NPLI)** using **White Rabbit (WR) Technology** based on the **Precision Time Protocol (PTP)**.
  • The infrastructure provides secure time synchronization for **5G/6G telecom networks**, **banking systems**, **smart power grids**, **transportation**, and **e-governance**.
  • Engineers completed a successful pilot test by sending timing signals between **RRSL Bengaluru** and the **NSE** facility in Chennai.
  • **White Rabbit Technology** improves the **IEEE 1588 Precision Time Protocol** by adding precise timestamps to standard Ethernet networks.
  • This technology syncs network points over fiber optic cables with accuracy ranging from **microseconds to nanoseconds**.
  • Unlike satellite systems like **GPS** that face spoofing and signal loss risks, fiber-based **White Rabbit Technology** offers strong protection against cyber threats.

Significance of Precision Time Dissemination

  • It provides tamper-proof time signals for essential sectors like **banking**, **5G/6G telecom**, **power grids**, and **transportation**.
  • Recognizing accurate time as **Digital Public Infrastructure (DPI)** protects stock trading algorithms and prevents timestamp manipulation during cyber attacks.
  • This initiative supports the **"One Nation, One Time"** mission and advances **Viksit Bharat** by reducing reliance on foreign satellite systems.
  • It strengthens **Legal Metrology** frameworks, simplifies business operations, and boosts global investor confidence in India's digital economy.

Time Generation and Dissemination of Indian Standard Time (IST)

  • **CSIR-NPL** generates **UTC (NPLI)** to maintain **IST**, linking national time to the **BIPM** in France.
  • The laboratory calculates **IST (UTC+5:30)** using **five caesium atomic clocks** and **three hydrogen masers** to achieve precision within **±2.8 nanoseconds**.
  • **Caesium atomic clocks** ensure long-term stability, while **hydrogen masers** maintain accurate short-term timing.
  • **GNSS** technology uses satellite signals to keep time synchronized at nanosecond precision with global standards.
  • **TWSTFT** uses geostationary satellites to transfer precise time, supporting **NavIC** and international time networks.
  • The **Network Time Protocol (NTP)** distributes **IST** over the internet via **time.nplindia.org** for government and private systems.
  • Cybersecurity agency **CERT-In** requires critical computer infrastructure to synchronize with **NPL** or **NIC** time servers.

CSIR–National Physical Laboratory (CSIR–NPL)

  • Parliament established **CSIR-NPL** in **1947** as the official **National Measurement Institute (NMI)** of India.
  • The laboratory maintains national measurement standards and **IST**, making Indian measurements recognized internationally.
  • Under **Make in India**, it develops quantum standards and offers calibration services to industries, defense units, and research centers.
  • Key focus areas include **Metrology**, **Quantum Science**, **Nanotechnology**, **Materials Science**, and **Environmental Monitoring**.
