Do you have a public announcement on the web, or some other source, that we can cite? Well AARI weekly publishes Antarctic events summaries here: https://www.aari.ru/press-center/news/rae .
But I am not sure if my case will be mentioned there.
This web page still says that Vostok time is UTC+07: https://www.aari.ru/ekspeditsii/rossiyskaya-antarkticheskaya-ekspeditsiya-(r... Could you please fix that web page? That would help confirm the change, so that when people ask us for our source, we can direct them to aari.ru.
Does "00:00" mean 00:00 local time, or 00:00 UTC?
My bad, sorry, I missed this point.
Local time, of source.
OK. Did clocks jump back from 00:00 today to 22:00 the previous day, or from 02:00 to 00:00 today? Also, could you please briefly say why Vostok changed from UTC+07 to UTC+05? I would like to document this in commentary.
Has local time at Vostok been UTC+6 ever since 1957, or has it changed before?
No. At least since my antarctic career start, 10 years ago, Vostok base has UTC+7.
Ouch. TZDB has been wrong for Vostok for at least 10 years. I will try to correct this. (I hope you have not been at Vostok for 10 years! I'd rather live in Siberia, or even in Nebraska. I can joke about this, as I was born in Nebraska....) Attached is a draft patch to TZDB to implement these changes. Please let us know if you see problems with it. I have not installed this patch into the TZDB development repository as it is still preliminary.
