This timestamp is milvus logic ts value, you could convert it into time with following logic:

const (
	logicalBits     = 18
	logicalBitsMask = (1 << logicalBits) - 1
)

func ParseTS(ts uint64) (time.Time, uint64) {
	logical := ts & logicalBitsMask
	physical := ts >> logicalBits
	physicalTime := time.Unix(int64(physical/1000), int64(physical)%1000*time.Millisecond.Nanoseconds())
	return physicalTime, logical
}

Awesome, thanks for your support
