Answer 1

And this one works

DateTimeFormatter formatter
= new java.time.format.DateTimeFormatterBuilder()
        .append( java.time.format.DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss") )
        .appendOptional(
                new java.time.format.DateTimeFormatterBuilder()
                    .appendLiteral('.')
                    .appendValue( ChronoField.MICRO_OF_SECOND, 1, 6, SignStyle.NOT_NEGATIVE).toFormatter())
        .toFormatter();
