Android time in iso 8601

using android and joda time lib - I'm trying to convert the user's time zone to format it later: 2012-11-12T21: 45: 00 + 02: 00, for example.

DateTimeZone zone = DateTimeZone.forID( TimeZone.getDefault().getID());

the above code does not work - does anyone know how I can take Europe / London (Timezone.getID) and convert it to an offset so that I can put it in ISO 8601 format?

If I understand your purpose correctly, you can directly use the SimpleDateFormat class.

Code example:

 SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ", Locale.UK); String formattedDate = sdf.format(new Date());

You can see the documentation in SimpleDateFormat

Sincerely.

API Level 26 added support for many time and date classes from Java. Now this solution can also be applied: fooobar.com/questions/188560 / ...

 // works with Instant Instant instant = Instant.now(); System.out.println(instant.format(DateTimeFormatter.ISO_INSTANT)); // works with ZonedDateTime ZonedDateTime zdt = ZonedDateTime.now(); System.out.println(zdt.format(DateTimeFormatter.ISO_INSTANT)); // example output 2014-09-02T08:05:23.653Z
