The latest changes in the algorithms for the formation of the International Atomic Time (TAI) scale are reported in terms of estimating the weights of the clocks involved in the formation of TAI. The characteristics of the long-term instability of new-generation hydrogen frequency and time standards from the State Primary Standard of time and frequency units and national time scale, GET 1-2018, were studied. The study was based on the results of processing the frequency difference with respect to TAI. It is confirmed that presently, new-generation hydrogen standards of frequency and time show significantly less long-term instability compared with similar and other quantum frequency standards.
