# 53.34. pg\_timezone\_names \#

檢視表 `pg_timezone_names` 提供 `SET TIMEZONE` 所辨識的時區名稱清單，以及相關縮寫、UTC 偏移量與日光節約時間狀態。（嚴格而言，PostgreSQL 不使用 UTC，因為它不處理閏秒。）與 [`pg_timezone_abbrevs`](/internals/views/view-pg-timezone-abbrevs.md) 顯示的縮寫不同，其中許多名稱隱含一組日光節約時間轉換日期規則。因此，相關資訊會隨當地 DST 邊界改變。顯示的資訊是根據 `CURRENT_TIMESTAMP` 的目前值計算。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.postgresql.tw/internals/views/view-pg-timezone-names.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
