I want to extend a discussion I started on the Reddit Android Dev community yesterday with a new question: How do you manage an up-to-date timezone database shipped with your app using the JodaTime library on a device that has outdated timezone information? The problem The specific issue at hand relates to a particular timezone, "Europe/Kaliningrad". And I can reproduce the problem: On an Android 4.4 device, if I manually set its time zone to the above, calling new DateTime() will set this DateTime instance to a time one hour before the actual time displayed on the phone's status bar. I

I am trying to implement Joda-Time to count down to Christmas, but so far I'm struck. I tried java.util.Date and most StackOverflow questions and answers suggested to use Joda-Time. But I can't get it working. Some codes give different answers. Here are some codes I tried, DateTime now = new DateTime(); DateTime christmas = new DateTime(2012, 12, 25, 8, 0, 0, 0); Days daysToChristmas = Days.daysBetween(today, christmas); System.out.println(daysToChristmas.toString()); And this prints P187D as answer. DateTime start = new DateTime(DateTime.now()); DateTime end = new DateTime(2012, 12, 25, 0, 0,

I am using hibernate 4 with joda time and spring data jpa. Spring data provides annotations @CreadedOn @LastModifiedOn i am trying to use these two annotations.Below is a snapshot of my pojo @Entity @Table(name="restaurant") @Audited public class Restaurant { @Id @GeneratedValue(strategy = GenerationType.AUTO) private long id; private String restaurantName; @CreatedDate @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime") // @Type(type = "org.jadira.usertype.dateandtime.threetenbp.PersistentDateTime") private DateTime createdOn; @LastModifiedDate @Type(type = "org.jadira

Is it possible to create a date in JodaTime and then make Quartz schedule the job using the JodaTime object? Can we give a Period jodaPeriod to Quartz API in order to run a task for a particular period in a day? Are the two APIs related and/or compatible in any way? The AxonFramework has a QuartzEventScheduler which looks like it does what you want. Here's the downlaod page and it's under the Apache 2.0 license. Quartz provides a pretty comprehensive API that you could extend anyway you wanted. The hook you would need to create would be against the Trigger interface, I've created one before

How can I convert Date to DateTime and vice versa? E.g. Date dt = new Date(); Now I want to covert this to DateTime . Also DateTime dtim = new DateTime(); Now I want to convert it to Date. skaffman Is this Joda Time 's DateTime you're talking about? If so, it will be dateTime.toDate() I guess you convert it to UTC via Date.getTime(). And after that, use a constructor/setter on the other object. As skaffman said above dateTime.toDate() should do the trick. But keep in mind that if the dateTime object had a different timezone than the user's current timezone, dateTime.toDate() will return the

I have dates in the format 20Jan2013, 08Aug2012 etc, with their own specific timezones. So for example, 20Jan2013 might have a timezone ID of Australia/Melbourne, and 08Aug2012 might have an ID of Europe/London. What I want to do is, based on these timezones and the dates, calculate the UTC offset for that timezone on the given date. I've come up with this so far: DateTimeFormatter dtf = DateTimeFormat.forPattern("ZZ"); DateTimeFormatter dtf1 = DateTimeFormat.forPattern("ddMMMYYYY"); DateTimeZone zone = DateTimeZone.forID("Australia/Melbourne"); DateTime thisDate = dtf1.parseDateTime(
