问题 I've tried the following to no avail: new Period(Years.ONE).getDays(); new Period(1, 0, 0, 000).getDays(); The answer I want is obviously 365. 回答1: If you want the real number of days for a given year: int year = 2012; LocalDate ld = new LocalDate(year,1,1); System.out.println(Days.daysBetween(ld,ld.plusYears(1)).getDays()); Of course, this returns 365 or 366... normally: int year = 1582; LocalDate ld = new LocalDate(year,1,1,GJChronology.getInstance()); System.out.println(Days.daysBetween(ld

问题 How to control TimePicker, I just want to show time range in time picker from 08:00 am to 02:00 pm (except from 08:00 am to 02:00 pm hide all) I have written complete code to show TimePicker, and customized time as well. Here is my code: case DIALOG_TIME: final Calendar c = Calendar.getInstance(); int hour = c.get(Calendar.HOUR_OF_DAY); int minute = c.get(Calendar.MINUTE); // Create a new instance of TimePickerDialog and return it return new TimePickerDialog(this, lisTime, hour, minute,

问题 I'm using Spring Framework for my services API and org.joda.time.DateTime for datetime parsing. Specifically, I'm using the ISOFormatter.dateOptionalTimeParser() , which allows users the flexibility to use just the date, or both date and time, which is a requirement. Believe me, I've seen all these related questions that I can already tell people are going to point me towards, e.g. this and this, etc. Previously, I was taking the date as String and then processing it using the joda formatter

问题 I ran into a strange issue. Here is a snippet of code that describes it: DateTimeZone dtz = DateTimeZone.forOffsetHours(0); DateTime dt = new DateTime(dtz); System.out.println(dt); System.out.println(dt.toDate()); the output is: 2012-02-29T17:24:39.055Z Wed Feb 29 19:24:39 EET 2012 I'm located UTC+2, but this action is supposed to create a java.util.Date object which is initialized for UTC time. What am I missing? 回答1: Date doesn't know about a time zone at all - it only represents an instant

问题 I need to import the current date and time into a MySQL database field whose format is TimeStamp. From examining sample data, it seems that the format for the MySQL TimeStamp datatype is "yyyy-mm-dd hh:mm:ss". I am using Joda-Time formatting in my spring hibernate application. How do I get the current date time in a format that will be accepted by the underlying MySQL TimeStamp formatted field? Here is my current code, which will not compile because eclipse says .parseDateTime() requires a

问题 let's assume I have following dates (in String): 2009-05-15T23:00:00 2009-05-15T23:00:00.000Z 2009-05-15 I don't care about the time and zone, only date is relevant for me. So I want to try to parse it with following pattern: yyyy-MM-dd I try to parse it using Joda-Time: DateTimeFormat = DateTimeFormat.forPattern("yyyy-MM-dd"); format.withZone(zone).parseDateTime(string).toLocalDate(); and I get following exception: java.lang.IllegalArgumentException: Invalid format: "2009-05-15T23:00:00.000Z

问题 I have an object Shift , with two fields: startDateTime and endDateTime as DateTime from Joda-Time. And my shift includes Daylight Saving UK change. It starts on 25/03/2017 13:00 and ends on 26/03/2017 02:00 (basically should end on 26/03/2017 01:00 , but this date does not exists, and endDate is shifted +1 hour). According to this site: When local standard time was about to reach Sunday, 26 March 2017, 01:00:00 clocks were turned forward 1 hour to Sunday, 26 March 2017, 02:00:00 local

问题 I'm having a weird problem right now. When I insert todays date into database, it's mapped into yesterdays date, it happens with every date. For example, when I try to insert 2016-09-02, database saves it as 2016-09-01. Here is my mapping: @DateTimeFormat(pattern="dd/MM/yyyy") @Column(name = "OrderDate", nullable = false) @Type(type="org.jadira.usertype.dateandtime.joda.PersistentLocalDate") private final LocalDate orderDate; I create instances by new LocalDate() I tried printing the value on

问题 I'm reading in csv-files with in one column a string that should be converted to a datetime. The string is in the form MM/dd/yyyy HH:mm . However when I try to transform this using joda-time, I always get the error: Exception in thread "main" java.lang.UnsupportedOperationException: Schema for type org.joda.time.DateTime is not supported I don't know what exactly the problem is... val input = c.textFile("C:\\Users\\AAPL.csv").map(_.split(",")).map{p => val formatter: DateTimeFormatter =
