NEW DELHI: The Indian government has commissioned a demonstration network using advanced “White Rabbit” precision timing technology to deliver a secure, tamper-resistant national time signal. This initiative aims to reduce reliance on foreign timing sources for critical national infrastructure.
Union Minister for Consumer Affairs, Food and Public Distribution Pralhad Joshi launched the network last week at the Regional Reference Standard Laboratory (RRSL) in Bengaluru. The project is a collaborative effort involving the Department of Consumer Affairs, the CSIR-National Physical Laboratory (CSIR-NPL), and the Indian Space Research Organisation (ISRO).
What is White Rabbit Technology?
White Rabbit is an advanced open-source timing system originally developed at CERN for high-energy physics experiments. It is an enhanced version of the Precision Time Protocol (PTP) that enables sub-nanosecond synchronisation accuracy over standard fibre-optic Ethernet networks.
The technology combines hardware timestamping and Synchronous Ethernet to achieve extremely precise time and frequency distribution, making it ideal for applications requiring ultra-accurate, tamper-resistant timing.
High-Precision Synchronisation for Critical Sectors
The system distributes Indian Standard Time (IST), traceable to the national time-keeping standard UTC (NPLI), through Precision Time Protocol (PTP) based on White Rabbit technology.
This offers sub-nanosecond level accuracy and enhanced security, making it suitable for sectors such as banking, telecommunications, power grids, transportation, and digital governance.
As part of the rollout, a successful verification test was conducted for secure time transmission between the Bengaluru laboratory and the National Stock Exchange’s (NSE) facility in Chennai.
The project involved close coordination with CSIR-NPL, ISRO, the Securities and Exchange Board of India (SEBI), NSE, and BSNL.
Part of the ‘One Nation, One Time’ Initiative
On July 16, Minister Joshi visited ISRO’s Bengaluru headquarters to review progress on the broader Indian Standard Time Dissemination Project. This falls under the government’s “One Nation, One Time” initiative.
Mr. Joshi emphasised that a trusted indigenous time source is now essential digital infrastructure. It supports consumer protection, fair trade, cyber resilience, and the reliability of financial markets, telecom, and power systems.
The minister described the project as a key step toward technological self-reliance under the Viksit Bharat vision. It will help position India among global leaders in precision time dissemination while reducing dependence on external timing sources.
Nidhi Khare, Secretary of the Department of Consumer Affairs, noted that the initiative, alongside reforms in legal metrology rules, would enhance consumer confidence, facilitate easier business operations, and support the country’s digital transformation.
Strategic Importance
In an era of increasing digitalisation and cyber threats, precise and secure time synchronisation is foundational for modern infrastructure.
Accurate timing is critical for financial transactions, telecom networks, power grid stability, and various digital services. By developing an indigenous capability, India strengthens its cyber resilience and ensures greater sovereignty over critical time signals.
This demonstration network represents an important milestone in building robust, homegrown solutions for national timing needs. Its successful implementation could pave the way for wider deployment across the country in the coming years.
