The files ftp://elsie.nci.nih.gov/pub/tzcode1998c.tar.gz and ftp://elsie.nci.nih.gov/pub/tzcode1998c.tar.gz are now available. These incorporate the proposed changes circulated by Paul Eggert on the time zone mailing list a few days ago (save the "French correction," on which I'll wait for the dust to settle); also included are the symlink changes circulated earlier this year and changes and additions to Arts.htm. --ado

proposed tz changes for Brazil DST, Asia/Gaza, tzfile.5, and comments
by Paul Eggert Feb. 27, 1998

Feb. 27, 1998

It's time to update tz, as the clocks in much of Brazil do not currently agree with what tz claims. Here's a proposed patch that address the following issues that have accumulated over time. * Update the rules for Brazil's summer of 1997-1998, thanks to Daniel C. Sobral <dcs(a)gns.com.br>. Now the Pope is getting into the daylight-saving act! * Change Asia/Gaza to use Jordan's DST rules starting in 1996, and observe the Zion rules from 1940 through 1947, as suggested by Amos Shapir <amos(a)nsof.co.il>. * Mention size of reserved-for-future-use space in tzfile.5, as suggested by Denis Excoffier <Denis.Excoffier(a)ens.fr>. * The CIA no longer claims that Uzbekistan has two time zones, so remove commentary dismissing that claim. * Use comment headings that reflect the ISO country code table more accurately for UK/Eire, Denmark, Faeroe, Greenland, Svalbard, Jan Mayen, China, Taiwan, Korea (North and South), US minor outlying islands, and French Southern & Antarctic Lands. This was suggested by Dave Skinner <dave(a)kirdu.jpl.nasa.gov>. Palestine is still a special case; it has no ISO country code but has its own section regardless, as I expect it to get a country code eventually. * Update and correct URLs, some of which have become outdated. I still have two big tasks in my in-box: Law's data and Olson's suggestion for automatically maintaining last-changed times; these will have to wait until I get more free time. =================================================================== RCS file: RCS/antarctica,v retrieving revision 1998.2 retrieving revision 1998.2.1.1 diff -c -r1998.2 -r1998.2.1.1 *** antarctica 1998/01/17 19:27:24 1998.2 --- antarctica 1998/02/27 02:12:05 1998.2.1.1 *************** *** 51,60 **** 6:00 - MAWT # Mawson Time # References: # <a href="http://www.antdiv.gov.au/aad/exop/sfo/casey/casey_aws.html"> ! # http://www.antdiv.gov.au/aad/exop/sfo/casey/casey_aws.html (1996-07-15) # </a> # <a href="http://www.antdiv.gov.au/aad/exop/sfo/mawson/video.html"> ! # http://www.antdiv.gov.au/aad/exop/sfo/mawson/video.html (1996-04-19) # </a> # Brazil - year-round base --- 51,60 ---- 6:00 - MAWT # Mawson Time # References: # <a href="http://www.antdiv.gov.au/aad/exop/sfo/casey/casey_aws.html"> ! # Casey Weather (1998-02-26) # </a> # <a href="http://www.antdiv.gov.au/aad/exop/sfo/mawson/video.html"> ! # Mawson Station, Antarctica (1998-02-25) # </a> # Brazil - year-round base *************** *** 78,84 **** # don't observe daylight saving time, even if Terre Adelie supplies came # from Tasmania. # ! # French Southern Territories with year-round inhabitants # # Martin-de-Vivies Base, Amsterdam Island, -374105+0773155, since 1950 # Alfred-Faure Base, Crozet Islands, -462551+0515152, since 1964 --- 78,84 ---- # don't observe daylight saving time, even if Terre Adelie supplies came # from Tasmania. # ! # French Southern & Antarctic Lands with year-round inhabitants # # Martin-de-Vivies Base, Amsterdam Island, -374105+0773155, since 1950 # Alfred-Faure Base, Crozet Islands, -462551+0515152, since 1964 *************** *** 104,110 **** 10:00 - DDUT # Dumont-d'Urville Time # Reference: # <a href="http://www.icair.iac.org.nz/science/reports/fr/IFRTP.html"> ! # Support and Development of Polar Research and Technology (1996-09-10) # </a> --- 104,110 ---- 10:00 - DDUT # Dumont-d'Urville Time # Reference: # <a href="http://www.icair.iac.org.nz/science/reports/fr/IFRTP.html"> ! # Support and Development of Polar Research and Technology (1997-02-03) # </a> *************** *** 212,220 **** # at that time (1957).

It was never formally annexed to Egypt, + # though. + # + # The rest of Palestine was under Jordanian rule at that time, formally + # annexed in 1950 as the West Bank (and the word "Trans" was dropped from + # the country's previous name of "the Hashemite Kingdom of the + # Trans-Jordan"). So the rules for Jordan for that time apply. Major + # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and + # East Jerusalem. + # + # Both areas were occupied by Israel in June 1967, but not annexed (except + # for East Jerusalem). They were on Israel time since then; there might + # have been a Military Governor's order about time zones, but I'm not aware + # of any (such orders may have been issued semi-annually whenever summer + # time was in effect, but maybe the legal aspect of time was just neglected). + # + # The Palestinian Authority was established in 1993, and got hold of most + # towns in the West Bank and Gaza by 1995.

Squiggle is an indispensable tool for preparing "viewer friendly" CAD-generated designs and illustrations. For a limited time, we are offering Squiggle for only $49.00 - a savings of over 50% off our regular price. Squiggle enables you to create drawings that are more approachable, allowing your clients to feel more comfortable with your design process. Squiggle works with all the popular CAD programs, allowing you to transform HPGL and HPGL/2 plot files into hand-drawn art in a matter of minutes. Squiggle allows for the customization of variable line combinations, and allows the user to vary the width and color of up to 255 lines with an unlimited number of hand drawn styles to each line. You can choose from a range of seven preset styles that range from "carefully sketched with a drafting pen" to "scribbled on the back of a napkin." Each line is drawn independently, and results are not precisely predictable- just like drawing done by the human hand. Styles can be combined into one image and pen effects can be can be saved into templates to create custom, "in-house" styles.

Therefore the rules given for Israel for that period, apply there too. (Though I find the name "Zion" rather inappropriate -- why not just call it "Israel" or "Palestine"?) The Gaza Strip was under Egyptian rule between 1948/5/15 until 1967/6/5 (except a short occupation by Israel from 1956/11 till 1957/3, but no time zone was affected then). It was never formally annexed to Egypt, though. The rest of Palestine was under Jordanian rule at that time, formally annexed in 1950 as the West Bank (and the word "Trans" was dropped from the country's previous name of "the Hashemite Kingdom of the Trans-Jordan"). So the rules for Jordan for that time apply. Major towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and East Jerusalem. Both areas were occupied by Israel in June 1967, but not annexed (except for East Jerusalem). They were on Israel time since then; there might have been a Military Governor's order about time zones, but I'm not aware of any (such orders may have been issued semi-annually whenever summer time was in effect, but maybe the legal aspect of time was just neglected). The Palestinian Authority was established in 1993, and got hold of most towns in the West Bank and Gaza by 1995. I know that in order to demonstrate some manner of independence, they have been switching to summer time and back on a different schedule than Israel's, but I don't know when this was started, or what algorithm is used (most likely the Jordanian one). To summarize, the table should probably look something like that: Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996- ------------+-----------+-----------+-----------+----------- Israel | Zion | Zion | Zion | Zion West bank | Zion | Jordan | Zion | Jordan Gaza | Zion | Egypt | Zion | Jordan I guess more info may be available from the PA's web page (if/when they have one). -- Amos Shapir Paper: nSOF Parallel Software, Ltd.
