32 # From Paul Eggert (2006-03-22):
33 #
34 # A good source for time zone historical data outside the U.S. is
35 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
36 # San Diego: ACS Publications, Inc. (2003).
37 #
38 # Gwillim Law writes that a good source
39 # for recent time zone data is the International Air Transport
40 # Association's Standard Schedules Information Manual (IATA SSIM),
41 # published semiannually. Law sent in several helpful summaries
42 # of the IATA's data after 1990.
43 #
44 # Except where otherwise noted, Shanks & Pottenger is the source for
45 # entries through 1990, and IATA SSIM is the source for entries afterwards.
46 #
47 # Another source occasionally used is Edward W. Whitman, World Time Differences,
48 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
49 # I found in the UCLA library.
50 #
51 # A reliable and entertaining source about time zones is
52 # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).

2067 # Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
2068 # with Shapir and assume that it observed DST from 1940 through 1947,
2069 # and that it used Jordanian rules starting in 1996.
2070 # We don't yet need a separate entry for the West Bank, since
2071 # the only differences between it and Gaza that we know about
2072 # occurred before our cutoff date of 1970.
2073 # However, as we get more information, we may need to add entries
2074 # for parts of the West Bank as they transitioned from Israel's rules
2075 # to Palestine's rules. If you have more info about this, please
2076 # send it to tz@elsie.nci.nih.gov for incorporation into future editions.

2082 # last week, the PLO Authority (PA) has decided not to turn its clocks

2084 # the PA has decided to implement DST in April.

34 # A good source for time zone historical data outside the U.S. is
35 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
36 # San Diego: ACS Publications, Inc. (2003).
37 #
38 # Gwillim Law writes that a good source
39 # for recent time zone data is the International Air Transport
40 # Association's Standard Schedules Information Manual (IATA SSIM),
41 # published semiannually. Law sent in several helpful summaries
42 # of the IATA's data after 1990.
43 #
44 # Except where otherwise noted, Shanks & Pottenger is the source for
45 # entries through 1990, and IATA SSIM is the source for entries afterwards.
46 #
47 # Another source occasionally used is Edward W. Whitman, World Time Differences,
48 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
49 # I found in the UCLA library.
50 #
51 # For data circa 1899, a common source is:

53 # <http://www.jstor.org/stable/1774359>.

521 # Kong. [According] to the DST record from Hong Kong Observatory (actually,
522 # it is not [an] observatory, but the official meteorological agency of HK,
523 # and also serves as the official timing agency), there are some missing
524 # and incorrect rules. Although the exact switch over time is missing, I
525 # think 3:30 is correct. The official DST record for Hong Kong can be
