zoneddatetime

I have this method to calculate midnigt and current time as long values: /** * Returns the time range between the midnight and current time in milliseconds. * * @param zoneId time zone ID. * @return a {@code long} array, where at index: 0 - midnight time; 1 - current time. */ public static long[] todayDateRange(ZoneId zoneId) { long[] toReturn = new long[2]; LocalTime midnight = LocalTime.MIDNIGHT; LocalDate today = LocalDate.now(zoneId); LocalDateTime todayMidnight = LocalDateTime.of(today, midnight); ZonedDateTime todayMidnightZdt = todayMidnight.atZone(zoneId); toReturn[0] =

I'm parsing a ZonedDateTime using like this: @JsonSerialize(using = ZonedDateTimeSerializer.class) private ZonedDateTime expirationDateTime; I need to be able to properly deserialize this date. However, there is no deserializer for this that is provided by jackson: com.fasterxml.jackson.datatype.jsr310.deser Is there a reason why it's missing? What is the most common workaround? Updated : Here is my scenario: I create ZonedDateTime like this: ZonedDateTime.of(2017, 1, 1, 1, 1, 1, 1, ZoneOffset.UTC) Then I serialize the object that contains the date like this: public static String toJSON(Object

I am using Java 8 This is what my ZonedDateTime looks like 2013-07-10T02:52:49+12:00 I get this value as z1.format(DateTimeFormatter.ISO_OFFSET_DATE_TIME) where z1 is a ZonedDateTime . I wanted to convert this value as 2013-07-10T14:52:49 How can I do that? Is this what you want? This converts your ZonedDateTime to a LocalDateTime with a given ZoneId by converting your ZonedDateTime to an Instant before. LocalDateTime localDateTime = LocalDateTime.ofInstant(z1.toInstant(), ZoneOffset.UTC); Or maybe you want the users system-timezone instead of hardcoded UTC: LocalDateTime localDateTime =

I have an object of ZonedDateTime that is constructed like this ZonedDateTime z = ZonedDateTime.of(LocalDate.now().atTime(11, 30), ZoneOffset.UTC); How can I convert it to LocalDateTime at time zone of Switzerland? Expected result should be 16 april 2018 13:30 . How can I convert it to LocalDateTime at time zone of Switzerland? You can convert the UTC ZonedDateTime into a ZonedDateTime with the time zone of Switzerland, but maintaining the same instant in time, and then get the LocalDateTime out of that, if you need to. I'd be tempted to keep it as a ZonedDateTime unless you need it as a

I have a simple application with Spring Boot and Jetty. I have a simple controller returning an object which has a Java 8 ZonedDateTime : public class Device { // ... private ZonedDateTime lastUpdated; public Device(String id, ZonedDateTime lastUpdated, int course, double latitude, double longitude) { // ... this.lastUpdated = lastUpdated; // ... } public ZonedDateTime getLastUpdated() { return lastUpdated; } } In my RestController I simply have: @RequestMapping("/devices/") public @ResponseBody List<Device> index() { List<Device> devices = new ArrayList<>(); devices.add(new Device("321421521"
