MySQL Timestamp/LocalDateTime/Instant @Versionin precission is 1 sec

[Tomas-Kraus]

@Versionin precission is 1 sec is quite a long time those days.
There are few places in the code which need changes:

MySQLPlatform:

    @Override
    public ValueReadQuery getTimestampQuery() {
        if (timestampQuery == null) {
            timestampQuery = new ValueReadQuery();
            timestampQuery.setSQLString("SELECT NOW(3)");
            timestampQuery.setAllowNativeSQLQuery(true);
        }
        return timestampQuery;
    }

Currently there is "SELECT NOW()" with default 1 sec precision. This query is being used to retrieve timestamp from the server.

But changing it to return value including miliseconds causes DatabaseQueryMechanism method updateObjectForWriteWithChangeSet() to throw an exception because

    int rowCount = updateObject();

call of updateObject() returns 0.

MySQLPlatform method appendTimestamp(java.sql.Timestamp, Writer) also produces SQL fragment with 1 sec precision and there may be few more places in this class.
