need to update to latest timezone data (2016h) to pick up Turkey DST rule change

Key information

• Joda-Time version 2.9.4
• Result of TimeZone.getDefault() sun.util.calendar.ZoneInfo[id=“UTC”,offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
• Result of DateTimeZone.getDefault() UTC

Problem description

Latest version of Joda-Time does not include 2016g timezone data. Specifically, it doesn’t reflect Turkey’s decision to permanently remain on UTC+3 (See http://www.oracle.com/technetwork/java/javase/tzdata-versions-138805.html: Turkey switched from EET/EEST (+02/+03) to permanent +03, effective 2016-09-07.)

Test case

Scala code below:

import org.joda.time._

val turkeyTz = DateTimeZone.forID("Europe/Istanbul")

val now = new DateTime(turkeyTz)
val offsetNow = turkeyTz.getOffset(now) / 1000 / 60

val later = new DateTime(2016, 10, 30, 5, 0, turkeyTz)
val offsetLater = turkeyTz.getOffset(later) / 1000 / 60

Current output:

turkeyTz: org.joda.time.DateTimeZone = Europe/Istanbul
now: org.joda.time.DateTime = 2016-10-27T19:57:06.583+03:00
offsetNow: Int = 180
later: org.joda.time.DateTime = 2016-10-30T05:00:00.000+02:00
offsetLater: Int = 120

Expected output is that offsetLater is also 180

Joda-Time users are expected to be able to follow these instructions to keep the time-zone data up to date. A new release will occur at some point, but I never make commitments as to when.

Your documentation (https://www.joda.org/joda-time/timezones.html) still says that there is: +02:00 | Europe/Istanbul | Asia/Istanbul, Turkey
