Clock tickSeconds() method in Java with Examples

Last Updated : 08 Jun, 2020

method is a static method of Clock class that returns a clock that returns the current instant ticking in whole Seconds using the best available system clock and zone of instant is same as the instant passed as a parameter. The returned clock is also immutable, thread-safe, and Serializable and this method is equivalent to tick(system(zone), Duration.ofSeconds(1)).

public static Clock tickSeconds(ZoneId zone)

This method takes a mandatory parameter

, which is the time-zone to use to round off instant of a clock in the whole Second.

This method returns a clock that returns the current instant ticking in whole Second with zone same as zone passed as parameter.

Code:
ZoneId zoneId = ZoneId.of("Asia/Calcutta");
Clock clock = Clock.tickSeconds(zoneId);
System.out.println(clock.instant());

Output:
2018-08-21T20:22:32Z

Explanation::
method tickSeconds() returns the instant 
which ticks in a whole Second means 
nanosecond field is zero.

Below programs illustrates tickSeconds() method of java.time.Clock class:

When Clock is created with Zone Kolkata and printing instant of the clock ticking in whole Second.

// Java program to demonstrate
// tickSeconds() method of Clock class

import java.time.*;

// create class
public class tickSecondsMethodDemo {

    // Main method
    public static void main(String[] args)
    {
        // Zone Id with Zone Asia/Calcutta
        ZoneId zoneId = ZoneId.of("Asia/Calcutta");

        // create a clock which ticks in the whole Second
        Clock clock = Clock.tickSeconds(zoneId);

        // print instance of clock
        System.out.println(clock.instant());
    }
}

Print the date and Time of clock with zone Europe/Paris and clock ticks per whole Second.

// Java program demonstrate
// tickSeconds() method of Clock class

import java.time.*;

// create class
public class tickSecondsMethodDemo {

    // Main method
    public static void main(String[] args)
    {

        // Zone Id with Zone Europe/Paris
        ZoneId zoneId = ZoneId.of("Europe/Paris");

        // create a clock which ticks in the whole Second
        Clock clock = Clock.tickSeconds(zoneId);

        // get ZonedDateTime object to print time
        ZonedDateTime time = clock
                                 .instant()
                                 .atZone(clock.getZone());

        // print time variable value
        System.out.println("Date and Time :" + time);
    }
}

Date and Time :2018-08-22T13:27:41+02:00[Europe/Paris]
