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

[Tomer Cohen]

According to 'timedatectl' command, my system is set to remove the DST
bit in a month from now, which means that Ubuntu  users didn't suffer
from today catastrophe, but if these users will be naive and think that
their machines are up-to-date, it'd hit them when no one will alert
enough time in advance, on October 6th.

$ timedatectl 
      Local time: א' 2013-09-08 15:52:00 IDT
  Universal time: א' 2013-09-08 12:52:00 UTC
        Timezone: Asia/Jerusalem (IDT, +0300)
     NTP enabled: yes
NTP synchronized: no
 RTC in local TZ: no
      DST active: yes
 Last DST change: DST began at
                  ו' 2013-03-29 01:59:59 IST
                  ו' 2013-03-29 03:00:00 IDT
 Next DST change: DST ends (the clock jumps one hour backwards) at
                  א' 2013-10-06 01:59:59 IDT
                  א' 2013-10-06 01:00:00 IST


We need this emergency fix as soon as possible, because users are
starting to look for workarounds, and not all these workarounds are good
enough for daily use, and these workarounds could break packages when an
update will arrive.

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'
