Abstract :
A zero baseline interferometry (ZBI) experiment was conducted to determine the differential instrumental delay between two stations (Kashima, Japan, and Richmond, USA). It enabled the authors to find an absolute time comparison with an accuracy of better than 1 ns. ZBI experiments in Japan were conducted in winter and summer to find the delay dependency on temperature
