Abstract
The determination of time by east and west observation of the zenith distance of a star near the prime vertical shows discrepancies as much as 2 seconds of time. A new method with higher accuracy has been developed. It is based on observation of an individual pair of stars. The observation of each star (one east, the other west of the meridian) consists of determining the instant of time at which it crosses a fixed preselected unknown zenith in order to determine the circumstances when greatest accuracy can be expected.
