Date: Fri, 19 Apr 96 15:20:03 EDT From: ado@elsie.nci.nih.gov (Arthur David Olson) Changes to Bangalore, the People's Republic of China, and Chuuk/Truk may follow. The Bangalore report was a false alarm: its author had set TZ='GMT+5', which behaves differently in modern tz versus 1989 tz due to the fact that modern tz complies with Posix. (The correct TZ setting for Bangalore is 'India/Calcutta', but that wasn't his problem.) Also, the recent message about China from cml1001@cus.cam.ac.uk (William C.M. Leung) was about an older version of tz; tzdata96f already reflects the changes he's talking about. The Chuuk/Truk report sounded right, though. A change is proposed below. It retains the name `Truk' for the time zone name, since it is the traditional English name for the area and is still in common use. The proposed change also moves recently added notes around in `australasia' so that they're at the end, as the file's first comment suggests. I also got private email from a correspondent in the Tengiz oil fields of western Kazakhstan, and enclose a proposed new time zone Asia/Aktau. His comments suggest that my earlier guesses were wrong about Asia/Yerevan so I've changed the guesses. While I was at it I added proposed commentary about time zones for which we lack solid data (in Mongolia and Uzbekistan) and a proposed comment giving an alternate name for Rangoon. =================================================================== RCS file: RCS/asia,v retrieving revision 1996.2 retrieving revision 1996.2.1.1 diff -c -r1996.2 -r1996.2.1.1 *** asia 1996/01/27 20:44:36 1996.2 --- asia 1996/04/19 23:01:35 1996.2.1.1 *************** *** 34,39 **** --- 34,40 ---- # 4:00 YSK YSD Yerevan (was 3:00)* # 4:00 GST GDT Gulf* # 4:30 AFT Afghanistan* + # 5:00 ASK ASD Aktau (was SHSK, SHSD)* # 5:00 ASK ASD Ashkhabad (was 4:00)* # 5:00 BSK BSD Bishkek (was 6:00) (was FSK, FSD)* # 5:00 PKT Pakistan* *************** *** 82,93 **** 4:30 - AFT # Armenia # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Yerevan 2:58:00 - LMT 1924 May 2 3:00 - YSK 1957 Mar 4:00 Russia YS%s - # Shanks has Yerevan switching to 3:00 (with Russian DST) in spring 1991, - # but usno1995 has Armenia at 4:00 (with DST).
