1.addtime中有一条是openGauss自身省略时间末尾0导致，另一条是openGauss中time类型非严格模式时，限定范围为’838:59:59’。在函数参数中，对99991231解析时openGauss非严格模式将其认为是超范围时间，将其限定到’838:59:59’，而后参与运算，mysql则将其视为不合法时间。（已经过Sig专家确认）。
2.convert_tz中有18条是因为openGauss中时区比mysql中要多。（已经过Sig专家确认）
3.timestampdiff中有8条是因为，0年在openGauss中是闰年，在mysql中是平年，导致了运算日期差一天。（已经过Sig专家确认）
