In this paper, a proof-of-concept experiment for IEEE1588 PTP-based Indian standard time dissemination through a dark telecom optical fiber in the central Delhi region has been reported. This is the first such demonstration of IST through terrestrial optical fibers and should provide redundancy to popular satellite based time distribution in India.
