Frequencies of frequency standards are shifted by the local static gravity red shifts and also modulated by the tidal relativistic red shifts. We compute the tidal relativistic red shifts using a time-domain method and present the numerical results for the National Institute of Metrology（NIM） in Beijing, Laboratoire National de Metrologie et Essais-Systeme de References Temps-Espace（LNE-SYRTE） in Paris and Physikalisch-Technische Bundesanstalt（PTB） in Braunschweig. The differences of the tidal relativistic red shift approach as large as 1.1×10-16 when frequency standards at NIM are compared with those at SYRTE and PTB. Moreover, the tidal relativistic red shifts of frequency standards in space stations are also computed.
