Hello all,
I came across http://www.jroller.com/scolebourne/entry/why_jsr_310_isn_t.
1) I am currently migrating Java Calendar to joda-time. I was wondering, should I use threeten instead of joda-time? Is threeten production ready?
2) Can threeten library and joda-time libraries exist together in a same application? As I am using some 3rd…
I have a field in a form to state the time duration of an event.
Say, the event is to last 15 mins. So the field will have the following value: 00:15
If it is to last 1 hour: 01:00, etc.
How can I create a Joda Duration object with the string "HH:MM"?
Looking at Joda Time home page, it mentions that it is possible to create a Duration…
My entities currently contain java Date properties. I'm starting to use Joda Time for date manipulation and calculations quite frequently. This means that I'm constantly having to convert my Dates into Joda DateTime objects and back again.
So I was wondering, is there any reason I shouldn't just change my entities to store Joda…
Has anyone gotten JODA time classes to work on Google Appengine? I'm using 1.3.4 of the java sdk and I get the following error when trying:
java.lang.NoClassDefFoundError: com/google/appengine/repackaged/org/joda/time/DateTimeZone
I've imported it as well:
import com.google.appengine.repackaged.org.joda.time.DateTime;
Hello
Does anyone know if there's a method in Joda Time or Java itself which takes either an int or a String as an argument, e.g. 4 or "4" and gives the name of the month back in short format, i.e. JAN for January?
I suppose long month names can be truncated and converted to upper case.
Thanks
Mr Morgan.
From DateTimeFormatter javadoc:
Zone names: Time zone names ('z') cannot be parsed.
Therefore timezone parsing like:
System.out.println(new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy").parse("Fri Nov 11 12:13:14 JST 2010"));
cannot be done in Joda:
DateTimeFormatter dtf = DateTimeFormat.forPattern("EEE MMM dd HH:mm:ss…
I'm using GWT on the client (browser) and Joda Time on the server. I'd like to perform some DB lookups bounded by the day (i.e. 00:00:00 until 23:59:59) that a request comes in, with the time boundaries based on the user's (i.e. browser) timezone.
So I have the GWT code do a new java.util.Date() to get the time of the request,…
I'm using the Joda-Time library with Java. I'm having some difficulty trying to turn a Period object to a string in the format of "x days, x hours, x minutes".
These Period objects are first created by adding an amount of seconds to them (they are serialized to XML as seconds and then recreated from them). If I simply use the…
I'm implementing a count-down using Joda Time. I only need a display accuracy of seconds.
However when printing the time, the seconds are displayed as full seconds, so when the count down reaches, for example, 900ms, then "0" seconds is printed, but as a count-down it would make more sense to display "1" second, until the…
I'd like to use Joda's DateTime for query parameters in Jersey, but this isn't supported by Jersey out-of-the-box. I'm assuming that implementing an InjectableProvider is the proper way to add DateTime support.
Can someone point me to a good implementation of an InjectableProvider for DateTime? Or is there an…
In my android program, I have a spinner that allows the user to select different times. Each selection is processed with Joda time to subtract the minutes. It works fine for minutes 0 to 59 and 61 and greater. However, when 60 minutes is subtracted, the time is not updated, and the original time is shown.
How do…
I would like to calculate end date (and time) of an event. I know starting date and duration (in minutes). But:
I have to skip holidays - non-recurrent situation
I have to skip weekends - recurrent situation
I have to not count working time (e.g: from 8:00am till 5:00pm) - recurrent situation, but with finer…
Hello,
DateTimeFormatter fmt = DateTimeFormat.forStyle('SS').withLocale(locale)
DateTime dt = fmt.parseDateTime("11/4/03 8:14 PM");
the above statement will parse the string correctly, and save as DateTime (Joda Time).
Now how to represent the beginning of a day. The below fails with
DateTime dt =…
Joda-Time library includes different datetime classes
DateTime - Immutable replacement
for JDK Calendar DateMidnight
- Immutable class representing a date where the time is forced to
midnight LocalDateTime -
Immutable class representing a local
date and time (no time zone)
I'm wondering…

I am using Joda Time library to convert my String dates to a real date, because this seemed like the easiest solution to do this. I am using the DateTime object to do this;
new DateTime(strValue);
But when inserting some formats it throws me the exception;

Say a month end date is the date in a month which is the last non-weekend and non-holiday day in that month. How can I find the most recent past month end date with Joda time? For example, the answer for today would be Friday 28th May because that was May's…
I am sure that someone familiar with HQL (I am myself a newbie) can easily answer this question.
In my Grails application, I have the following domain class.

Heya!
I'm using joda due to it's good reputation regarding multi threading. It goes great distances to make multi threaded date handling efficient, for example by making all Date/Time/DateTime objects immutable.

Why do we need three classes?
Which one performs better?
Why is dividing a Period or Duration or Interval instance not implemented? E.g. p = p.divideBy(2);
