	if t.Type == mysql.TypeTimestamp && loc != nil {
		t.Time = t.In(loc)
	}

		data = append(data, 11)
		data = append(data, dumpUint16(uint16(year))...)
		data = append(data, byte(mon), byte(day), byte(t.Hour()), byte(t.Minute()), byte(t.Second()))
		data = append(data, dumpUint32(uint32((t.Nanosecond() / 1000)))...)
	case mysql.TypeDate, mysql.TypeNewDate:
