Using ZonedDateTime.now(zoneId):T23:25:06.408922700+01:00 Using now():Īnd there is one more option where in you can use factory method now() of ZonedDateTime class. Using now(ZoneId zoneId):Īlternatively you can use factory method now(ZoneId zoneId) defined in ZonedDateTime class itself like below: ("Using ZonedDateTime.now(zoneId):" + ZonedDateTime.now(ZoneId.of("Europe/Amsterdam"))) Output: This gives me exact date time in Amsterdam. You can either adjust the instant created above to get the ZonedDateTime like below: Adjusting Instant object ("Using instant.atZone():" + instant.atZone(ZoneId.of("Europe/Amsterdam"))) Output: If you want to know date time, in your time zone, at a particular moment( represented by Instant) you can use ZonedDateTime. ("Current Date Time using Instant:" + instant) Output:Ĭurrent Date Time using Instant:T22:25:06.385917300Z Using ZonedDateTime Now coming back to current date-time using Instant, we need to use now() method as below: Instant instant = Instant.now() For example, If we are running a job and want to calculate the time for next run we would use Instant. – Countries like Ireland, Portugal, Ghana follows UTC time zone, which means UTC + 0įor complete list for all countries, you can check List of Countries with UTC time offsetsįor our back end calculations in Java, we use Instant. – A time in UTC (zone) itself, UTC + 0 is indicated by a Z( Z from Zulu time) It is similar to GMT(Greenwich mean time).Īll date times for specific Zones are calculated relative to UTC. Instant represents date time in UTC(coordinated universal time), so it does not consider specific Zone and it is number of nanoseconds elapsed since epoch or since. Which in other words means that if two Instant objects are created at the same moment in any part of world, they will have exactly same value. Using Instant, we can get the exact moment on timeline which is independent from time zones. If world cup is in Australia, then people in India can say that ,world cup started at different time than what what was time in Australia but it started at exact same moment on timeline for people of Australia as well as India. For example, if World cup is starting at certain moment, it is exact that moment for everyone living in any part of world. Let us see how we can get current date and time using these classes and how they are different from each other. ![]() Java 8 had come up with new set of classes for date and time under java.time package, which are: In this quick tutorial, we will see, how to get current date time using Java 8.
