# Environment.getServerTime

> 함수형 API `getServerTime`으로도 같은 기능을 쓸 수 있어요.

### 기능 설명

토스 앱 서버의 현재 시간을 Unix timestamp(밀리초)로 가져와요. 디바이스 시간이 아니라 서버 기준이라 클라이언트 시간 조작에 따른 치팅을 줄이는 데 도움이 돼요.

토스앱 Android/iOS `5.245.0` 이상에서 사용할 수 있어요. 호출 전에 `Environment.getServerTime.isSupported()`로 지원 여부를 확인할 수 있어요. 미지원 버전에서 호출하면 `UNSUPPORTED_APP_VERSION` 에러가 발생해요.

### 타입

```ts
Environment.getServerTime(): Promise<number>;
```

**Params**

없음

**Response**

서버 시간을 Unix timestamp(밀리초)로 반환해요. 예를 들어 `1705123456789`예요.

### 에러

에러 코드는 catch한 에러의 `error.code` 값이에요.

| 코드                        | 설명                                                                                                                                          |
| ------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- |
| `UNSUPPORTED_APP_VERSION` | 실행 중인 토스앱 버전이 이 기능을 지원하지 않으면 호출 즉시 발생해요. `Environment.getServerTime.isSupported()`로 사전 확인하고, 발생 시 `error.message`(업데이트 안내 문구)를 사용자에게 보여주세요. |

### 예시 코드

```js
import { Environment } from "@apps-in-toss/web-framework";

try {
  const serverTime = await Environment.getServerTime();
  console.log(serverTime);
} catch (error) {
  console.error(error);
}
```

## 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://developers-apps-in-toss.toss.im/documentation/sdk/domains-api/environment/environment.getservertime.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.
