Upcoming Gamma-Ray and Cosmic-Ray experiments require relative time calibration of all detector components with (sub-)nanosecond precision. White Rabbit, an established technology for time- and frequency transfer, can be applied here. We describe a White Rabbit (WR) based design for Tunka-HiSCORE - a timing array for Gamma-Ray astronomy now under construction. Sub-nsec synchronization results from cosmic ray data, in-situ calibrations and laboratory tests taken over several years are presented. A WR-based online array-trigger and shower reconstruction concept is outlined, aiming at improved physics sensitivity. We conclude that excellent field performance, design flexibility, cost-efficieny and its open source approach make WhiteRabbit advantageous over custom-made solutions for large, long-term projects.
