<p class="MsoNormal">I spot checked several of those – and there is no more daylight saving for those regions. Thus, the zone definition should contain a dash.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I noticed some more inconsistencies specific to the “asia” file. The data separator is flexible. Everywhere, the tab is used as a separator. Here, the tab and the space are used interchangeably. Also in all the other files, the “Zone”
is followed by a space and then the name. In this asia file, I noticed frequent use of tabs in between. Do you use space and tab alike?<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Hey there,<o:p></o:p></p>
<p class="MsoNormal">First of all, I would like to thank you. I have to implement something in JavaScript that uses timezones. However, I am using an older JS version that does not have the flexibility like today’s JS. So I was looking for a repository holding
all current timezones and rules for it, rather then me, checking time and again how which timezone is configured
<span style="font-family:"Segoe UI Emoji",sans-serif">😉</span> This really could help me. Reading through the files, it sometimes made me chuckle and I was actually surprised how fluent timezones are handled. Changes almost every year…<o:p></o:p></p>
<p class="MsoNormal">I would like to recommend some improvements. I know you have pretty stable release by now. I am aware that changes probably to the structure might affect a lot of people/projects. However…<o:p></o:p></p>
<p class="MsoNormal">First of all, a tar.gz is Linux specific. True, you could install additional Windows software. But, that might not go well with customers of mine. I think a ZIP would be acceptable for both worlds.<o:p></o:p></p>
<p class="MsoNormal">Since I was interested in the repository, I downloaded the “Data only distribution”. I found six files containing the TZ information. And I found 27 files, containing other stuff. Well, there might be three or four files in a grey zone
(calendars, backlist…). But I definitely do not consider MAKEFILE and .awk file as part of a “data only distribution”. Maybe move them to a separate folder in the GZ file?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Finally, I got one more recommendation/question. I had read the readme file but it didn’t explain the data I saw in the files. It took me a while to understand the concept of the data structure. Some info of what to see in the file,
and how to read it would help.<o:p></o:p></p>
<p class="MsoNormal">And I think the first line of the ZONE definition contains some inconsistency (maybe I still didn’t understand it correctly). Below is a screenshot. See the first line for the zones? It looks mismatched with the New York. The RULE and
the [UNTIL] are probably in the wrong column. Format is probably missing.<o:p></o:p></p>
<p class="MsoNormal"><img width="530" height="136" style="width:5.5208in;height:1.4166in" id="Picture_x0020_2" src="cid:image002.png@01D674B5.472618F0"><o:p></o:p></p>
<p class="MsoNormal">Then I noticed that the open-end validity. For rules it is denoted as “max” and for zones it is just a <blank>. Could we get some consistency here?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">And finally here comes my question: In the rules, I see in the column several times denoted with a tailing “u” or “s”. I think I read on one occasion that the times are denoted in “standard time”. I do not recall anymore where that was.
But regardless, <o:p></o:p></p>
<ol style="margin-top:0in" start="1" type="a">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo3">I don’t understand what that “denoted in standard time” would mean<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo3">I definitely have no clue would the tailing “u”: would imply.<o:p></o:p></li></ol>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can you shed some light on this?<o:p></o:p></p>
