Why is the flight card prompt time of Huawei mobile assistant later than the SMS time?

The data of situation intelligent flight card comes from flight attendants, and the results will be displayed on the card only after the flight attendants' data is returned. The return departure time of flight steward is the possible actual departure time summarized by big data analysis and historical data. So it is different from the planned departure time mentioned in the short message, so I suggest you take the actual departure time as the standard.
