// Program to illustrate the from() method

import java.util.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoField;

public class GfG {
    public static void main(String[] args)
    {
        ChronoLocalDateTime date
            = LocalDateTime
                  .from(ZonedDateTime.now());
