I am dealing with something very similar to what has been asked here - compare Joda-Time time zones but it does not seem to work for me. Here's a piece of code which I am testing Joda-Time DateTime with - DateTime estDT = new DateTime(DateTimeZone.forID("America/Puerto_Rico")).withMillisOfSecond(0); DateTime londonDT = new DateTime(DateTimeZone.forID("Europe/London")).withMillisOfSecond(0); System.out.println("Comparison " + londonDT.isBefore(estDT)); System.out.println("Comparison " + londonDT.isAfter(estDT)); Interestingly enough, I get 'false' from both the sysout statements above. Can

I want to convert a Joda Time UTC DateTime object to local time. Here's a laborious way to do it which seems to work. But there must be a better way. Here's the code (in Scala) without surrounding declarations: val dtUTC = new DateTime("2010-10-28T04:00") println("dtUTC = " + dtUTC) val dtLocal = timestampLocal(dtUTC) println("local = " + dtLocal) def timestampLocal(dtUTC: DateTime): String = { // This is a laborious way to convert from UTC to local. There must be a better way. val instantUTC = dtUTC.getMillis val localDateTimeZone = DateTimeZone.getDefault val instantLocal = localDateTimeZone

This question is about deserialization to Joda-Time DateTime using jackson-datatype-joda module for Jackson . Is there a default timezone that date strings will be deserialized into? If so, what is it? Is it UTC ? I need to ask this because the Jackson documentation is not specific for Joda-Time DateTime. I found in this article ( http://wiki.fasterxml.com/JacksonFAQDateHandling ) that Jackson will assume GMT as the default time zone for deserializing into java.util.Date or java.util.Calendar . However, there is no mention of Joda-Time data types in this document. In addition, I specifically

This question already has answers here : JodaTime equivalent of DateUtils.truncate() (4 answers) I am pulling timestamps from a file that I want to create a new DateTime for, but I want to create the DateTime at the floor of the hour (or any Joda Period will do). How Can I do this? Wohoo, found it. Simple like everything in Joda once I traced down the calls. DateTime dt = new DateTime().hourOfDay().roundFloorCopy(); 来源： https://stackoverflow.com/questions/1207957/how-do-i-create-a-new-joda-datetime-truncated-to-the-last-hour

Is it possible to get the pattern string from a joda-time DateTimeFormatter? DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyyMMdd"); String originalPattern = formatter. ??? Joda Time does not provide a way to get the original pattern from a DateTimeFormatter. One reason is probably that a DateTimeFormatter wasn't necessarily created from a pattern; for example DateTimeFormat.forStyle() does not use patterns at all. However if you always use patterns, then you could wrap the DateTimeFormat class to record the pattern when the DateTimeFormatter is constructed. That way you can look

I'm trying to simply add TimeZone information back into a LocalDate before performing some more calculations. The LocalDate came from using the ObjectLab LocalDateCalculator to add days to an existing DateTime but the method needs to return a modified ReadableInstant to form an Interval which I can then inspect. The code I'm trying amounts to a conversion of Joda LocalDate to Joda DateTime: LocalDate contextLocalBusinessDate = calculator.getCurrentBusinessDate(); DateTime businessDateAsInContextLocation = new DateTime(contextLocalBusinessDate, contextTimeZone); The error I get is from Joda's
