The zonedDateTime() method of java.time.chrono.IsoChronology class is used to retrieve the date and time of a particular zone according to Iso calendar from a particular instant. Syntax:
public ZonedDateTime zonedDateTime(Instant instant,
ZoneId zone)
Parameter: This method takes the following arguments as parameter.
- instant: which is the object of type instant
- zone: which is the object of type zoneId
Return Value: This method returns the date and time of a particular zone according to Iso calendar from a particular instant. Below are the examples to illustrate the zonedDateTime() method: Example 1:
Java
// Java program to demonstrate// zonedDateTime() methodimport java.util.*;import java.io.*;import java.time.*;import java.time.chrono.*;public class GFG { public static void main(String[] argv) { try { // creating and initializing LocalDate Object LocalDate hidate = LocalDate.now(); // getting IsoChronology used in LocalDate IsoChronology crono = hidate.getChronology(); // getting LocalDate and time for the // given Instant and ZoneId // by using zonedDateTime() method ChronoZonedDateTime<LocalDate> date = crono.zonedDateTime( Instant.now(), ZoneId.systemDefault()); // display the result System.out.println("LocalDate and time is: " + date); } catch (DateTimeException e) { System.out.println("passed parameter can " + "not form a date"); System.out.println("Exception thrown: " + e); } }} |
Output:
LocalDate and time is: 2020-03-10T02:37:13.036Z[Etc/UTC]
Example 2:

Output:
LocalDate and time is: 1970-01-01T06:56:40Z[Etc/UTC]
