Usage

From source file:Main.java

public static void main(String[] args) {
    Instant instant = Instant.parse("2014-12-03T10:15:30.00Z");
    System.out.println(instant.compareTo(Instant.now()));

}

From source file:Main.java

public static void main(String[] args) {
    Instant instant = Instant.now();

    Instant instantFromDateTime = LocalDateTime.now().toInstant(ZoneOffset.ofHours(-2));

    System.out.println(dateTimeFromInstant);

    System.out.println(instantFromDateTime);
}

From source file:Main.java

public static void main(String[] args) {
    Instant instant = Instant.parse("2014-12-03T10:15:30.00Z");

    Temporal t = instant.adjustInto(Instant.now());
    System.out.println(t);/*from w w w.j a v a  2s  . co m*/

}

From source file:Main.java

public static void main(String[] args) {
    Duration d1 = Duration.ofSeconds(55);
