I am planning to convert ZonedDateTime to instant as per the below logic. Say, I am in PST timeZone and the current time is 11A.M. If I convert now( no daylight saving as of today March 04 2018) and the toInstant will be 7P.M. For the same 11 A.M, the toInstant will return 6 P.M as of April 04 2018 as daylight saving will be observed. So, The below code returns correctly. ZonedDateTime dateTime = ZonedDateTime.now(); --->>> March 04th 2018 at 11 A.M PST dateTime.plusMonths(1).toInstant(); -->> returns April 04th 2018 at 6 PM PST as daylight saving will be observed But, The result will be

I reviewed many questions related to TimeZones on Stackoverflow, but I could not find the one to the problem I am struggling with: Why doesn't Joda's DateTimeZone.getDefault() return updated timezone on TZ change (after resuming an application?). TimeZone.getDefault() seems to be working just fine . Should I use DateTimeZone.forTimeZone(TimeZone.getDefault()) to get up to date Joda's DateTimeZone object? Here is how to replicate: Start app that prints both DateTimeZone.getDefault() and TimeZone.getDefault() : 09-15 16:46:59.512 14961-14961/com.example.android.whatever D/TimeZone: DateTimeZone

I wanted to get the number of weeks and months between two date range in Java. For ex., Start Date: 03/01/2012 End Date: 03/05/2012 Since the two dates fall in two different weeks I want the result to be 2 instead of 0. Second part of the problem is: Start Date: 02/29/2012 End Date: 03/01/2012 Number of months in between should be 2. I have been searching online regarding this and lot of people have recommended using Joda Date time in Java. So I gave it a shot. I was able to get the weeks working but I am not sure if this is the right way. Here is what I am doing to get the week duration:

This question already has an answer here: Number of days between two dates in Joda-Time 8 answers I need to get the difference in months between two dates, I'm using Joda Time, the problem is this: DateTime date1 = new DateTime().withDate(2015, 2, 1); DateTime date2 = new DateTime().withDate(2015, 1, 1); Months m = Months.monthsBetween(date1, date2); int monthDif = m.getMonths();//this return 0 it returns 0 because there is no month in the middle of the two dates, I need to return the difference in months not a few months in between, and add 1 would be problematic when the dates are the same.

How can we display the elapsed time with only 1 field. For example Period = 1 Year 4 Months and 5 Days ==> Result = "1 Year ago" Period = 3 Months 5 Days ==> Result = "3 Months ago" Period = 4 Hours 5 Minutes ==> Result = "4 Hours ago" So i just want the highest available field. There is no method in Joda-Time to do this, so you will have to test each field in turn manually. this will work val startDate = new DateTime(millis).withZone(dateTimeZone) val endDate = new DateTime(dateTimeZone) val period = new Period(startDate, endDate) val localized = PeriodFormat.wordBased(localeLanguageCode)
