Question

I have converted the dateTime given in specific timezone to UTC. for that I followed the below code.
My input dateTime is \"20121

Answer 1

I think the correct answer should be java.sql.Timestamp is NOT timezone specific. Timestamp is a composite of java.util.Date and a separate nanoseconds value. There is no timezone information in this class. Thus just as Date this class simply holds the number of milliseconds since January 1, 1970, 00:00:00 GMT + nanos.

In PreparedStatement.setTimestamp(int parameterIndex, Timestamp x, Calendar cal) Calendar is used by the driver to change the default timezone. But Timestamp still holds milliseconds in GMT.

API is unclear about how exactly JDBC driver is supposed to use Calendar. Providers seem to feel free about how to interpret it, e.g. last time I worked with MySQL 5.5 Calendar the driver simply ignored Calendar in both PreparedStatement.setTimestamp and ResultSet.getTimestamp.
