Time synchronization to sub-nsec precision of detector systems distributed over large areas is requested in modern astroparticle experiments, like upcoming Gamma-Ray and Cosmic-Ray detector arrays, to ensure optimal pattern recognition and background rejection. White-Rabbit (WR), a new ethernet-based technology for time and frequency transfer, is well suited for this purpose. It allows clock-synchronziation and trigger-time stamping to sub-nanosecond precision over multi-km scale distances. This technology also supports new complex and flexible topological trigger strategies, based on ethernet-routed timestamps. We present design and results from the White-Rabbit installation in the TAIGA-HiSCORE array, gained over several years; and discuss upcoming applications like e.g. the Cherenkov-Telescope-Array (CTA) and high energy neutrino telescopes. Excellent field performance, design flexibility at timing and triggering level, open soft- and hardware approach with strong community support and documentation, commercial availability, easy integration into modern system monitoring architectures, and the striking cost-efficiency make White-Rabbit a new de-facto experimental standard, and advantageous over custom-made solutions.
