Datetime behind an hour after insertion. Daylight savings

Question

I\'ve noticed that my MySql database is subtracting an hour from my DateTime objects when I insert certain dates to my tables. Example:

Insert: 2021-03-29 11:44:1         


        

Answer 1

Not sure why this was happening, but I fixed the problem by ditching Java.Sql.Timestamp in favour of Java.Time.LocalDateTime.

My insertion code now looks like below (where localDateTime is of type LocalDateTime rather than Timestamp):

jdbcTemplate.update(new PreparedStatementCreator() {
    @Override
    public PreparedStatement createPreparedStatement(Connection con) throws SQLException {
        PreparedStatement stmt = con.prepareStatement(
                "INSERT INTO Table (date) VALUES (?)");
        stmt.setObject(5,localDateTime));
        return stmt;
    }
});

The MySql database no longer automatically adjusts for timezone.
