title: Hibernate @CreationTimestamp @UpdateTimestamp for Calendar
body: <p>In my entity I have fields:</p>
  
  <pre><code>@UpdateTimestamp
  @Column
  private java.util.Calendar modifiedDate;
  @CreationTimestamp
  @Column
  private java.util.Calendar createdDate;
  </code></pre>
  
  <p>These fields are changed by hibernate. I see result saved to DB. In DB saved data without time, how I could explain to hibernate that calendar should be saved with current dateTime?</p>
  
  <hr>
  
  <p>P.S.
  I saw workarounds like method annotations <code>@PreUpdate</code> <code>@PrePersist</code> i do not think i need ones.</p>
