Why in News

  • A Union Minister recently launched the **Indian Standard Time (IST)** distribution demonstration network at the **Regional Reference Standards Laboratory (RRSL)** in **Jakkur, Bengaluru**.

What It Is

  • The **Jakkur** facility is India's first high-precision time distribution system that uses Ethernet cables and advanced protocols to share **Indian Standard Time (IST)** across digital networks.

Developed By

  • The **Legal Metrology Division** under the **Ministry of Consumer Affairs** leads this project together with **NPL**, **ISRO**, **BSNL**, and **SEBI**.

How It Works

  • **NPL** and **ISRO** create an independent **Indian Standard Time (IST)** reference, which reduces India's reliance on foreign **GPS** systems.
  • The system sends time signals through fibre-optic networks using the **IEEE 1588** precision time protocol standard for exact clock matching.
  • Connected devices automatically fix small time slips through phase-locking, maintaining timing accuracy down to less than **1 nanosecond**.

Key Features of White Rabbit Technology

  • The technology offers extremely accurate timing synchronization of less than **1 nanosecond** across all linked equipment.
  • It guarantees that timing data arrives at devices with predictable and fixed delays for smooth network operations.
  • The system can support thousands of devices across digital networks that stretch over **1,000 km**.
  • The network relies on open-source technology developed by **CERN**, allowing India to build its own customized solutions.

Strategic Applications

  • It protects defense, power grids, and nuclear plants from **GPS** spoofing and cyber timing attacks by using a local timing network.
  • Accurate time stamping helps stock markets and digital banking platforms prevent financial fraud and complete transactions safely.
  • The network provides essential timing support for **5G**, **6G**, quantum communication, and space missions to ensure fast data connections.
