java.sql.Timestamp 时区是特定的吗？ - Is java.sql.Timestamp timezone specific?

问题：

I have to store UTC dateTime in DB.我必须将 UTC dateTime 存储在 DB 中。
I have converted the dateTime given in specific timezone to UTC.我已将特定时区中给出的日期时间转换为 UTC。 for that I followed the below code.为此，我遵循了以下代码。
My input dateTime is "20121225 10:00:00 Z" timezone is "Asia/Calcutta"我输入的日期时间是“20121225 10:00:00 Z”时区是“亚洲/加尔各答”
My Server/DB(oracle) is running in the same timezone(IST) "Asia/Calcutta"我的服务器/数据库（oracle）运行在同一时区（IST）“亚洲/加尔各答”

Get the Date object in this specific Timezone获取此特定时区中的日期对象

        String date = "20121225 10:00:00 Z";
        String timeZoneId = "Asia/Calcutta";
        TimeZone timeZone = TimeZone.getTimeZone(timeZoneId);

        DateFormat dateFormatLocal = new SimpleDateFormat("yyyyMMdd HH:mm:ss z");
                    //This date object is given time and given timezone
        java.util.Date parsedDate = dateFormatLocal.parse(date + " "  
                         + timeZone.getDisplayName(false, TimeZone.SHORT));

        if (timeZone.inDaylightTime(parsedDate)) {
            // We need to re-parse because we don't know if the date
            // is DST until it is parsed...
            parsedDate = dateFormatLocal.parse(date + " "
                    + timeZone.getDisplayName(true, TimeZone.SHORT));
        }

       //assigning to the java.sql.TimeStamp instace variable
        obj.setTsSchedStartTime(new java.sql.Timestamp(parsedDate.getTime()));

Store into DB存入数据库

        if (tsSchedStartTime != null) {
            stmt.setTimestamp(11, tsSchedStartTime);
        } else {
            stmt.setNull(11, java.sql.Types.DATE);
        }

OUTPUT输出

DB (oracle) has stored the same given dateTime: "20121225 10:00:00 not in UTC. DB（oracle）存储了相同的给定dateTime: "20121225 10:00:00 not in UTC。

I have confirmed from the below sql.我已经从下面的 sql 中确认了。

     select to_char(sched_start_time, 'yyyy/mm/dd hh24:mi:ss') from myTable

My DB server also running on the same timezone "Asia/Calcutta"我的数据库服务器也在同一时区“亚洲/加尔各答”上运行

It gives me the below appearances它给了我以下外观

1. Date.getTime() is not in UTC Date.getTime()不是 UTC
2. Or Timestamp is has timezone impact while storing into DB What am I doing wrong here?或者时间戳在存储到数据库时有时区影响我在这里做错了什么？

One more question:还有一个问题：

Will timeStamp.toString() print in local timezone like java.util.date does? timeStamp.toString()会像java.util.date那样在本地时区打印吗？ Not UTC?不是UTC？
