[Bug 1158834] Re: Daylight saving dates for Asia/Jerusalem need updating

[MikeR]

Workaround:

create a temporary directory (I chose $HOME/dstfix) and cd into it

 ftp://ftp.iana.org/tz/data/asia
and download the text file
you should have a file named 'asia'

sudo su (get root privs.)
zic asia

to check whether the changes worked do
zdump -v  Asia/Jerusalem | grep 2013

My results:
zdump -v  Asia/Jerusalem | grep 2013
Asia/Jerusalem  Thu Mar 28 23:59:59 2013 UTC = Fri Mar 29 01:59:59 2013 IST isdst=0 gmtoff=7200
Asia/Jerusalem  Fri Mar 29 00:00:00 2013 UTC = Fri Mar 29 03:00:00 2013 IDT isdst=1 gmtoff=10800
Asia/Jerusalem  Sat Oct 26 22:59:59 2013 UTC = Sun Oct 27 01:59:59 2013 IDT isdst=1 gmtoff=10800
Asia/Jerusalem  Sat Oct 26 23:00:00 2013 UTC = Sun Oct 27 01:00:00 2013 IST isdst=0 gmtoff=7200

Then: 
cp /usr/share/zoneinfo/Asia/Jerusalem /usr/share/zoneinfo/Asia/Tel_Aviv
zdump -v  Asia/Tel_Aviv | grep 2013
Asia/Tel_Aviv  Thu Mar 28 23:59:59 2013 UTC = Fri Mar 29 01:59:59 2013 IST isdst=0 gmtoff=7200
Asia/Tel_Aviv  Fri Mar 29 00:00:00 2013 UTC = Fri Mar 29 03:00:00 2013 IDT isdst=1 gmtoff=10800
Asia/Tel_Aviv  Sat Oct 26 22:59:59 2013 UTC = Sun Oct 27 01:59:59 2013 IDT isdst=1 gmtoff=10800
Asia/Tel_Aviv  Sat Oct 26 23:00:00 2013 UTC = Sun Oct 27 01:00:00 2013 IST isdst=0 gmtoff=7200

exit

Title:
  Daylight saving dates for Asia/Jerusalem need updating

Status in “tzdata” package in Ubuntu:
  Confirmed

Bug description:
  The new POSIX definitions for daylight-saving in Israel are:
   # The law has been changed (2012-11-05): As of 2013, 
   # DST starts at 02:00 on the Friday before the last Sunday in March. 
   # DST ends at 02:00 on the first Sunday after October 1 
   # unless it occurs on the second day of the Jewish Rosh Hashana holiday, in which case,
   # DST ends a day later (i.e. at 02:00 the first Monday after October 1
   #Rule   NAME    FROM    TO      TYPE    IN      ON           AT      SAVE    LETTER/S
  Rule	Zion	      2013	     max     -         Mar      Fri>=23  2:00     1:00     D
  Rule	Zion	      2013	     2026    -        Oct       Sun>=2  2:00	     0          S
  Rule	Zion       2027	     only     -         Oct      4              2:00     0          S
  Rule	Zion	      2028	     2053    -        Oct      Sun>=2   2:00	     0          S

  In 2013 the change to DST is the same as before: 29-Mar-2013
  However the change to Standard time has moved from 28-Sep to 6-Oct

  This has been officially announced by the Knesset (Israeli parliament) but the documents are in Hebrew 
  I do not know whether this falls under 'bugs' or 'update request'
