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

[MikeR]

This has now become *urgent*
The legal position has zigzagged once agai. see:
ftp://ftp.cs.huji.ac.il/pub/tz/announcements/2013+law.pdf (in Hebrew)

The new rules are simpler, no longerlinked to the Jewish calendar:
 # As of 2013, DST starts at 02:00 on the Friday before the last Sunday
# in March.  DST ends at 02:00 on the last Sunday of October.
  
# 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	max	-	       Oct	lastSun	2:00	0      	S

For 2013, this means:
    Change IST to IDT on the Last Friday of March (29-Mar-2013) at 01:00
    Change IDT to IST on the Fourth Sunday of October (27-Oct-2013) at 02:00 (Was 7th of September)

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'
