The article says that GLONASS time counts days from zero to 1461, then resets back to zero. This is 4 years if we think leap year is once 4 years. But it is not. Leap year is once 4 years, but each 100 years it is not, except each 400 years it is. This is on average 365.2425 days per year not 365.25 days per year. Is GLONASS not long term thinking ahead enough?
