问题 Is it possible to get the previous and next DST transition timestamp with the Java Calendar/Date/TimeZone API? With Joda-Time I can write: DateMidnight today = new DateMidnight(2009, 2, 24); DateTimeZone zone = today.getZone(); DateTime previousTransition = new DateTime(zone.previousTransition(today.getMillis())); // 2008-10-26T02:59:59.999+02:00 for Europe/Berlin System.out.println(previousTransition); DateTime nextTransition = new DateTime(zone.nextTransition(today.getMillis())); // 2009-03

问题 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(); -->

问题 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How do you manage an up-to-date timezone database shipped with your app using the JodaTime library on a device that has outdated timezone information?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

问题 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");

问题 Is it possible to get the pattern string from a joda-time DateTimeFormatter? DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyyMMdd"); String originalPattern = formatter. ??? 回答1: 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

问题 My Domain object has couple of Joda-Time DateTime fields. When I'm reading database values using SimpleJdbcTemplate: Patient patient = jdbc.queryForObject(sql, new BeanPropertyRowMapper(Patient.class), patientId); It just fails and surprisingly, no errors were logged. I guess it's because of the timestamp parsing to DateTime is not working with Jdbc. If it's possible to inherit and override BeanPropertyRowMapper and instruct to convert all java.sql.Timestamp and java.sql.Date to DateTime , it
