Software-based time flipping detection

The invention discloses a method for detecting time flipping. The method may include receiving time data including week data and second data, and processing the time data to generate a first date. The method may include generating a second date based on the first date and an offset value, and obtaining a network date when the second date is earlier than a baseline date. The method may include assigning a network date as a baseline date, and processing the network date and a first date to determine an updated offset value. The method may include storing the updated offset value as an offset value, and determining a system date based on the network date. 本发明公开了一种用于检测时间翻转的方法。所述方法可以包括接收包括周数据和秒数据的时间数据，以及处理所述时间数据以生成第一日期。所述方法可以包括基于第一日期和偏移值生成第二日期，以及当第二日期早于基线日期时获得网络日期。所述方法可以包括将网络日期分配为基线日期，以及处理网络日期和第一日期以确定更新的偏移值。所述方法可以包括将所述更新的偏移值存储为偏移值，以及基于所述网络日期确定系统日期。
