jodatime

问题 The requirement is to simply to get the current wall time ( including the correct DST adjustment ) for a given Time Zone. There seems to be a few questions in SO hovering around this, but I can't seem to find a straight answer (in SO, Joda doco or googling) with a low friction way of getting the wall time. It seems like with the given inputs (current UTC time and desired TZ) I should be able to chain a couple methods from the Joda Time library to achieve what I want but there seems to be a

问题 I just started working with Joda-Time, and got it to correctly display my date in 24-hour clock ("military time") but I would rather it be am/pm. Looked it up and it mentioned hourOfDay which I figured was the HH value so I tried to write a loop that would break it down into AM/Pm but it never worked out. DateTime dtf = new DateTime(wikiParsedDate); if (hourOfDay == 00) { hourOfDay == 12; DateTimeFormatter builder = DateTimeFormat.forPattern( "dd-MM-yyyy HH:mm:ss.SS'AM" ); return builder

问题 With Joda library, you can do DateTimeFormat.forPattern("yyyy").parseLocalDate("2008") that creates a LocalDate at Jan 1st, 2008 With Java8, you can try to do LocalDate.parse("2008",DateTimeFormatter.ofPattern("yyyy")) but that fails to parse: Text '2008' could not be parsed: Unable to obtain LocalDate from TemporalAccessor: {Year=2008},ISO of type java.time.format.Parsed Is there any alternative, instead of specifically writing sth like LocalDate.ofYearDay(Integer.valueOf("2008"), 1) ? 回答1:

问题 I am seeing a a couple of errors coming up on Crittercism (Crash reporting service) for my published Android app. The trace is the following: 0 java.io.IOException: Resource not found: "org/joda/time/tz/data/ZoneInfoMap" ClassLoader: dalvik.system.PathClassLoader@45908320 1 at org.joda.time.tz.ZoneInfoProvider.openResource(ZoneInfoProvider.java:211) 2 at org.joda.time.tz.ZoneInfoProvider.<init>(ZoneInfoProvider.java:123) 3 at org.joda.time.tz.ZoneInfoProvider.<init>(ZoneInfoProvider.java:82)

问题 Can somebody please explain to me why when I try to get the milliseconds of a DateTime with a zone different from my own, it gives me back the milliseconds of my local machine's time zone? I'm looking to get the milliseconds of UTC, but my local settings of the application are set to EST (even though I'm actually in Ireland ;) ) Here's the code: DateTimeFormatter format = DateTimeFormat.mediumDateTime(); DateTime local = new DateTime(); DateTime utc = new DateTime(System.currentTimeMillis(),

问题 I am trying to change the value of Timestamp by DateTimeZone in Joda : DateTime dt = new DateTime(rs.getTimestamp("anytimestampcolumn"), DateTimeZone.forID("anytimezone")); Timestamp ts = new Timestamp(dt.getMillis()); For DateTime , value is : 2013-04-13T22:56:27.000+03:00 For TimeStamp , value is : 2013-04-13 22:56:27.0 Timestamp is coming without timezone difference. How can i get the correct Timestamp with TimeZone ? For example I want to get "2013-05-13 01:56:27.0". Thanks in advance.

问题 This question already has answers here : how to get a list of dates between two dates in java (22 answers) Closed 6 years ago . In my application user should select date from listview . The problem is generating this list. For example I need all dates between 2010-2013 or June-August (period maybe day , month , year ). Is there any method that allows to get that data? Example: I need dates between 01.01.2013 - 10.01.2013 01.01.2013 02.01.2013 03.01.2013 04.01.2013 05.01.2013 06.01.2013 07.01

问题 I want to compare two dates, however I'm running into trouble. 1 date is created from a java.util.date object and the other is manually crafted. The following code is an example: Date ds = new Date(); DateTime d = new DateTime(ds); DateTime e = new DateTime(2012,12,07, 0, 0); System.out.println(d.isEqual(e)); However the test turns out false . I am guessing that it is because of the time. How can I check if these two dates are equal to each other (I mean the Year, month, date are identical)?

问题 What's the standard way to work with dates and times in Scala? Should I use Java types such as java.util.Date or there are native Scala alternatives? 回答1: From Java SE 8 onwards, users are asked to migrate to java.time (JSR-310). There are efforts on creating scala libraries wrapping java.time for scala such as scala-time. If targeting lower than SE 8 use one of the below. Also see Why JSR-310 isn't Joda-Time A new Scala wrapper for Joda Time. This project forked from scala-time since it

问题 Anyone know of a Java library that can parse time strings such as "30min" or "2h 15min" or "2d 15h 30min" as milliseconds (or some kind of Duration object). Can Joda-Time do something like this? (I have an ugly long method to maintain that does such parsing and would like to get rid of it / replace it with something that does a better job.) 回答1: You'll probably have to tweak this a bit for your own format, but try something along these lines: PeriodFormatter formatter = new
