Hey, I have a es search with aggregations which contains date\_histogram with time\_zone parameter. When I'm choosing "Europe/Kyiv" as time\_zone I'm getting the following error reason: "Unknown time-zone ID: Europe/Kyiv". Any idea why it happens? Edit: Im using V8.1.3 ---

@leandrojmp I found this issue [[CI] JdbcFrozenCsvSpecIT 'Unknown time-zone ID' failures · Issue #95044 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/issues/95044#issuecomment-1637950541) might be relatd 🤔 ---

> [@Inbal](#): > > 8. **1**.3 Yeah, I think that's the issue then. 8.1.3 is from April 2022 according to this [blog post](https://www.elastic.co/blog/elastic-stack-8-1-3-released). _Europe/Kiev_ was renamed to _Europe/Kyiv_ in August 2022, on the 2022b release of tz data according to [this](https://mm.icann.org/pipermail/tz-announce/2022-August/000071.html). And [according to this](https://www.oracle.com/java/technologies/tzdata-versions.html) it was included on java versions from August 2022. But I'm not sure if just upgrading to a newer version or using a newer java will solve the issue. ---

Can you share your aggregation? Or at least the date\_histogram part. ---

Sure, ```auto "date_histogram": { "field": "timestamp", "calendar_interval": "day", "time_zone": "Europe/Kyiv" }, ``` I checked `Europe/Kiev` and it works. Ill try to upgrade, appreciate your help!! ---
