title: ResultSet.getTimestamp("date") vs ResultSet.getTimestamp("date", Calendar.getInstance(tz))
body: <p><code>java.util.Date</code>, <code>java.util.Timetamp</code> were seems to be causing great confusion for many. Within StackOverflow there are so many questions, Unfortunately my question is bit twisted.</p>
  
  <p>There are 2 JDBC api. How they should perform? Was there any consistencies among RDBMS’es?</p>
  
  <pre><code>ResultSet.getTimestamp("dateColumn") 
  ResultSet.getTimestamp("dateColumn", Calendar.getInstance(tz))
  </code></pre>
  
  <p>If someone has knowledge in Sybase, could you please share your experience?</p>
