The toString() method on this class does not take an argument. See [ZonedDateTime (Java SE 11 & JDK 11 )](https://docs.oracle.com/en%2Fjava%2Fjavase%2F11%2Fdocs%2Fapi%2F%2F/java.base/java/time/ZonedDateTime.html#toString())

Have a look at [https://www.baeldung.com/java-format-zoned-datetime-string](https://www.baeldung.com/java-format-zoned-datetime-string)

Try:

```auto
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MM.dd.yyyy HH:mm:ss");
String formattedString = (doc['field'].value).format(formatter);

```
