UTCTimeZoneShift

public class UTCTimeZoneShift extends TimeZone 

Represents the shift, i.e. the time difference between a time zone ‘X’ and the UTC+0 time zone.

This is used for (de-)serialization of ISO8601-compliant representations of UTC-relative time zones (e.g. +0100 for CEST)

getISO8601Offset

public static String getISO8601Offset(TimeZone timezone, long date)

Generate an ISO 8601 time zone offset string (e.g. +0200) for the given time zone at the given date.

The date is necessary to decide whether the time zone (e.g. Europe/Berlin) is in the daylight saving regime or not. In winter Europe/Berlin has a +0100 offset, in summer it is +0200.

Parameters:

timezone –
- the time zone in question.
date –
- the date for which the offset is to be calculated (unix time stamp).

Returns:

ISO 8601 time zone offset.
