Last Updated :
13 Dec, 2022
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
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
try {
LocalDate hidate = LocalDate.now();
IsoChronology crono = hidate.getChronology();
ChronoZonedDateTime<LocalDate> date
= crono.zonedDateTime(
Instant.now(),
ZoneId.systemDefault());
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:
Java
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
try {
LocalDate hidate = LocalDate.now();
IsoChronology crono = hidate.getChronology();
ChronoZonedDateTime<LocalDate> date
= crono.zonedDateTime(
Instant.ofEpochSecond( 25000 ),
ZoneId.systemDefault());
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: 1970-01-01T06:56:40Z[Etc/UTC]
