Union Minister Pralhad Joshi has launched a White Rabbit technology-based demonstration network at the Regional Reference Standard Laboratory (RRSL) in Bengaluru to securely distribute Indian Standard Time (IST) across the country.
The project is a collaborative effort between the Department of Consumer Affairs, the Council of Scientific and Industrial Research-National Physical Laboratory (CSIR-NPL), and the ISRO.
The network uses an advanced Precision Time Protocol (PTP)-based Ethernet network extension to deliver sub-nanosecond accuracy and microsecond-level synchronization over long distances. It is to be noted that the time signal is traceable to the Coordinated Universal Time (NPLI) (UTC (NPLI)).
