问题 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 . 回答1: 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

问题 I want to cast a ZonedDateTime object into a java.sql.Timestamp object without using the local date. For example, let's say I have the following datetime : System.out.println(myZonedDateTime); > 2018-09-02T23:55:05+04:00[Asia/Dubai] And my local timezone is UTC+08:00 I try to parse my ZonedDateTime to a Timestamp : Timestamp t = Timestamp.from(myZonedDateTime.toInstant()); System.out.println(t); > 2018-09-03 04:55:05.0 The value I get in my timestamp depends of my local time, when I want it

问题 I have code, similar to this: import java.time._ object app { def main (args :Array[String]) = { println("app started") // create two ZonedDateTime objects for 1st Jan 2018, 10am UTC // using separate methods val zdt1 = ZonedDateTime.of(2018, 1, 1, 10, 0, 0, 0, ZoneId.of("UTC")) val zdt2 = ZonedDateTime.parse("2018-01-01T10:00:00Z") println(s"COMPARING: $zdt1 and $zdt2") println("== check: " + (zdt1 == zdt2)) println(".equals check: " + (zdt1.equals(zdt2))) println(".isEqual check " + (zdt1

问题 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? 回答1: 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

问题 I am trying to replace the ZonedDateTime.toInstant method because it is only available since API 26 for Android. But my app is supposed to support API 19. I want to convert the ZonedDateTime to a Date so i can do something like this: final Calendar calendar = Calendar.getInstance(); calendar.setTime(new Date()); final long millis = calendar.getTimeInMillis(); What i want to achieve is the following: I want to calculate the difference between the current date and another date in Seconds,

问题 How to convert epoch like 1413225446.92000 to ZonedDateTime in java? The code given expects long value hence this will throw NumberFormatException for the value given above. ZonedDateTime.ofInstant(Instant.ofEpochMilli(Long.parseLong(dateInMillis)), ZoneId.of(TIME_ZONE_PST)); 回答1: Basil Bourque’s answer is a good one. Taking out the nanoseconds from the fractional part into an integer for nanoseconds may entail a pitfall or two. I suggest: String dateInMillis = "1413225446.92000"; String[]

问题 I've been trying to solve this problem without luck, hopefully someone could help me out... I created a DateUtil.java class which is placed within my project at: src/main/java/util/DateUtil.java I call "convertTime" method with the invoke component and on my laptop locally everything works fine but when deployed to an on-premise server I get the following error on the logs Root Exception stack trace: java.lang.NoClassDefFoundError: Could not initialize class java.time.zone.ZoneRulesProvider

问题 I'm querying a JSON API that returns something like this: { "created_time": "2017-01-05T16:32:29+0100", "updated_time": "2017-01-11T09:38:41+0100", "id": "23842536731240607" } I need to store the times in UTC format, but in order to change the timezone, I first need to parse it as a ZonedDateTime . To convert "+0100" to "+01:00" is easy enough. But how can I parse the (created/updated)_time into a ZonedDateTime so I can convert it to UTC? 回答1: Well let me break down the problem statement.

问题 How should I parse this datetime value that is in the PDT timezone? 06/24/2017 07:00 AM (PDT) I want to maintain the timezone so that I can then represent the time in other timezones depending on the website visitors preferences. I tried using ZonedDateTime but I get a parse error: java.time.ZonedDateTime.parse("06/24/2017 07:00 AM (PDT)") The error is: java.time.format.DateTimeParseException: Text '06/24/2017 07:00 AM (PDT)' could not be parsed at index 0 at java.time.format
