		// Format : dd-MM-yyyy HH:mm

		final LocalDateTime dateTime = LocalDateTime.now() ; //or something else.
		final int day = dateTime.getDayOfMonth();
		final int month = dateTime.getMonthValue();
		final int year = dateTime.getYear();
		final int hour = dateTime.getHour();
		final int minute = dateTime.getMinute();
		jsonGenerator.writeString(new StringBuilder()
					.append(day).append("-")
					.append(month).append("-")
					.append(year).append(" ")
					.append(hour).append(":")
