Question

When I insert new Date() object using jdbcTemplate to Oracle database, I can see that jdbc driver or Spring jdbcTemplate insert Date using local JVM offset.

SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy");
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
Date timeZoneDate = sdf.parse("09-SEP-1987");

For example when I insert Date object created in GMT this result to inserting 08-SEP-1987 in Oracle database if JVM timezone is USA.

Answer 1

Neither java.util.Date nor Oracle Date stores timezone information. In your case Jdbc driver converts your date using the JVM timezone. You can use one of the following options:

• If you are using PreparedStatement, you can use setDate(int
parameterIndex, Date x, Calendar cal) method to specify Calendar
  in UTC timezone.
• For Spring jdbcTemplate instead of inserting Date object, insert Calendar with UTC timezone
• TimeZone.setDefault(TimeZone.getTimeZone("GMT")) could be set on JVM lvl
• Use -Duser.timezone=GMT on JVM startup
