Europe/Berlin in Antarctica?

[RomanIakovlev]

I'm migrating https://github.com/RomanIakovlev/timeshape to the release 2018g, and found that some of my tests are broken due to changes in bounding boxes of certain time zones, particularly of Europe/Berlin. I see you've added Europe/Berlin to Antarctic territory as part of #42.

Unfortunately, I'm unable to understand the reason for doing so. You've posted several web links in the #42 to justify that, but in none of those pages Europe/Berlin is mentioned, at least explicitly. General web search also doesn't bring any more clarity. Could you please provide more details on why you have assigned Europe/Berlin to that segment of world in Antarctic?

The 2nd link (https://encyclopedia.timegenie.com/time_zones/antarctica/) has a section about Germany stations in Antarctica and suggests that Neumayer Station is UTC/GMT +1. This is the same time as Europe/Berlin, so that is why it was coded as Europe/Berlin. As you mentioned though, there isn't much certainty since Europe/Berlin isn't explicitly mentioned, but that entry on that website seemed to be the most credible source of information on the timezone in Antarctica in that area. If a more credible source exists that says otherwise please re-open this issue.

Certainly lacks certainty in whether they follow Europe/Berlin DST changes

They are on UTC all year. The other page is incorrect.

It should be simply Etc/UTC.

@mj1856 +1 for the second link with the information directly from the station inhabitants. I've also sent them (AWI) an email with the same question a couple of days ago, after finding about this issue, but got no reply yet. I'll post here if I'll get any. But anyway, I guess it makes sense to at least re-open this issue, which I can't do myself. @evansiroky would you mind re-opening it?

[evansiroky]

Thanks for the tz mailing list archive link, @mj1856 . I'll make this area be Etc/UTC.

I got confirmation via email

Dear Mr ********,

it's UTC (like for most Antarctic stations) - as you can also see via
the Neumayer webcam:

Message Hello, I'm interested to know what time zone is observed where Neumayer Station III is located and do you also observe Daylight Saving Time.

I'm helping to build a better timezone map on github https://github.com/evansiroky/timezone-boundary-builder

There seems to be a lot uncertainty about this station. The current consensus is that it follows Europe/Berlin time including its DST changes.

It would be great if you could shed some light on the issue.

Thank you,
Ugis

Lol, I've just got exactly the same answer from them, word for word. We have probably spammed them a bit. :) But great to get another confirmation anyway.
