TL;DR: In this article, a short-term combined clock correction forecasting method under a condition of uncertain forecasting duration is presented, and the method comprises the following steps that: obtaining an original clock correction sequence, and carrying out differential processing; according to the original clock corrections sequence, calculating a clock correction data quality factor, and determining the forecasting duration; adopting at least two types of clock corrections forecasting methods to carry out forecasting learning; calculating the weight value of each clock correction forecast method; calculating a combined clock corrections forecast value; judging whether time synchronization is established again or not at any time in
