java.time.Clock.tickSeconds(ZoneId zone) 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)).
Syntax:
public static Clock tickSeconds(ZoneId zone)
Parameters: This method takes a mandatory parameter zone, which is the time-zone to use to round off instant of a clock in the whole Second.
Return Value: This method returns a clock that returns the current instant ticking in whole Second with zone same as zone passed as parameter.
Example:
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:
Program 1; 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 classpublic 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()); }} |

Program 2: 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 classpublic 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); }} |
