Overview
- The demonstration White Rabbit Precision Time Protocol network was commissioned at the Regional Reference Standard Laboratory in Bengaluru and was announced on July 18.
- The system delivers Indian Standard Time traceable to the national time authority (NPLI/UTC) using a fibre‑based PTP protocol that corrects transmission delays to keep clocks in near‑nanosecond alignment.
- Authorities completed a verification transmission test between the RRSL Bengaluru node and the National Stock Exchange facility in Chennai to show secure, end‑to‑end time dissemination.
- The project is led by the Department of Consumer Affairs with CSIR‑NPL and ISRO and involved SEBI, NSE and BSNL as stakeholder participants in the tests.
- Officials say a domestic timing network will reduce reliance on foreign satellite timing, strengthen cyber resilience for consumers and markets, and require wider rollout and interagency coordination to reach critical infrastructure nationwide.
