CrudRepository custom find by current timestamp

I have table Bound

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "boundId", unique = true, nullable = false)
private long boundId;

@Column
@Basic
private Timestamp startTimeStamp;

@Column
@Basic
private Timestamp endTimeStamp;

And i created query :

public interface BoundsDataRepository extends CrudRepository<Bound, Long> {

@Query("from Bound b where b.startTimeStamp s <=:currentTimeStamp and b.endTimeStamp e>=:currentTimeStamp")
List<Bound> findByCurrentTimeStamp(Timestamp currentTimeStamp);

}

I’s give me an error. How should I name this query and how can I resolve this question?

Thanks for help!
