@TennyZhuang hi, PTAL The Time type has compare function, is it same with ==? also, it has getCoreTime function. What the difference among A==B, A.compare(B) and A.getCoreTime==B.getCoreTime?

[xiongjiwei]

CoreTime.compare function use first 60bit to compare time, which is same with uint64(a)&coreTimeBitFieldMask
