timezone-offset

I am using a query to get some application Received Date from Oracle DB which is stored as GMT. Now I have to convert this to Eastern standard/daylight savings time while retrieving. I am using the below query for this: select to_char (new_time(application_recv_date,'gmt','est'), 'MON dd, YYYY') from application It works fine for Standard time. But for daylight savings time we need to convert it to 'edt' based on timezone info. I am not very sure on how to do this. Please help me out You can use this query, without having to worry about timezone changes. select to_char(cast(application_recv

TZUpdater 2.1.0 is failing with tzdata2016g release. For Java 8 it fails with "Source directory does not contain file: VERSION" error, while it completes with "JRE updated to version : tzdataunknown" comment for Java 7. The reason of this seems to be recent change of IANA tzdata distribution: Unsetting VERSION field of Makefile. There is a bug reported regarding the issue: https://bugs.openjdk.java.net/browse/JDK-8166928 . DST date(30th October 2016) is getting closer and we at least need a workaround for this. Is it, somehow, possible? Workaround: Update Makefile of http://www.iana.org/time

I need to parse a String in the following format 2015-01-15-05:00 to LocalDate(or smth else) in UTC. The problem is that the following code: System.out.println(LocalDate.parse("2015-01-15-05:00", DateTimeFormatter.ISO_OFFSET_DATE)); outputs 2015-01-15 ignoring the offset. The desired output is 2015-01-16 Thanks in advance! The simplest answer is to use OffsetDateTime to represent the data, but you need to default the time: DateTimeFormatter fmt = new DateTimeFormatterBuilder() .append(DateTimeFormatter.ISO_OFFSET_DATE) .parseDefaulting(ChronoField.HOUR_OF_DAY, 0) .toFormatter(); OffsetDateTime

No, I'm not talking about zone offsets --- those can vary during the year for a region based on e.g. DST. I'm talking about the actual time zones maintained by IANA . I understand these are not supported by ISO 8601, correct? What are platforms doing to support identifying time zones in ISO 8601-like string representations? I notice that the latest Java date/time library is using an extended ISO 8601 format for this, e.g. 2011-12-03T10:15:30+01:00[Europe/Paris] . (See DateTimeFormatter API .) Is there some converging convention (e.g. with other languages and platforms) for extending ISO 8601

I'm trying to map the values that come from the Front-End to ZoneId class like this: Optional.ofNullable(timeZone).map(ZoneId::of).orElse(null) For most time zones it works fine, however, for some values Java throws exception: java.time.zone.ZoneRulesException: Unknown time-zone ID: America/Punta_Arenas However, it is a valid time-zone according to IANA: https://www.iana.org/time-zones Zone America/Punta_Arenas -4:43:40 - LMT 1890 I was thinking about using offset for such time-zones (just to hardcode values), but I guess there should be more convenient way to solve the issue. Is there a way
