时区请求和响应

时区

时区 API 请求以网址字符串形式构建。该 API 返回地球上由纬度/经度对所指定地点的时区数据。请注意，可能无法获得水上（如大洋或海上）位置的时区数据。

时区请求采用以下格式：

https://maps.googleapis.com/maps/api/timezone/outputFormat?parameters

其中，outputFormat 可以是以下值之一：

json（推荐），表示以 JavaScript 对象标记 (JSON) 格式输出；或
xml，指示以 XML 格式输出，结果包装在 <TimeZoneResponse> 节点内。

注意：网址必须编码正确方有效，并且对于所有网络服务，均有 16384 字符数限制。请在构建网址时注意这一限制。请注意，不同的浏览器、代理和服务器可能同样具有不同的网址字符限制。

Required parameters

location
A comma-separated latitude,longitude tuple, location=39.6034810,-119.6822510, representing the location to look up.
timestamp
The desired time as seconds since midnight, January 1, 1970 UTC. The Time Zone API uses the timestamp to determine whether or not Daylight Savings should be applied, based on the time zone of the location.
Note that the API does not take historical time zones into account. That is, if you specify a past timestamp, the API does not take into account the possibility that the location was previously in a different time zone.

Optional parameters

language
The language in which to return results.
- See the list of supported languages. Google often updates the supported languages, so this list may not be exhaustive.
- If language is not supplied, the API attempts to use the preferred language as specified in the Accept-Language header.
- The API does its best to provide a street address that is readable for both the user and locals. To achieve that goal, it returns street addresses in the local language, transliterated to a script readable by the user if necessary, observing the preferred language. All other addresses are returned in the preferred language. Address components are all returned in the same language, which is chosen from the first component.
- If a name is not available in the preferred language, the API uses the closest match.
- The preferred language has a small influence on the set of results that the API chooses to return, and the order in which they are returned. The geocoder interprets abbreviations differently depending on language, such as the abbreviations for street types, or synonyms that may be valid in one language but not in another. For example, utca and tér are synonyms for street in Hungarian.

时区示例

此部分包括的一些示例查询展示了 API 的功能。

以下查询请求获得美国内华达州的时区。时间戳设置为 2012 年 3 月 8 日。

网址

https://maps.googleapis.com/maps/api/timezone/json
  ?location=39.6034810%2C-119.6822510
  &timestamp=1331161200
  &key=YOUR_API_KEY

cURL

curl -L -X GET 'https://maps.googleapis.com/maps/api/timezone/json?location=39.6034810%2C-119.6822510&timestamp=1331161200&key=YOUR_API_KEY'

JSON

{
  "dstOffset": 0,
  "rawOffset": -28800,
  "status": "OK",
  "timeZoneId": "America/Los_Angeles",
  "timeZoneName": "Pacific Standard Time",
}

XML

<TimeZoneResponse>
 <status>OK</status>
 <raw_offset>-28800.0000000</raw_offset>
 <dst_offset>0.0000000</dst_offset>
 <time_zone_id>America/Los_Angeles</time_zone_id>
 <time_zone_name>Pacific Standard Time</time_zone_name>
</TimeZoneResponse>

以下查询请求获得美国内华达州的时区。位置与以上请求相同，但时间戳设置为 2012 年 3 月 15 日。响应现在包括了夏令时偏移。

网址

https://maps.googleapis.com/maps/api/timezone/json
  ?location=39.6034810%2C-119.6822510
  &timestamp=1331766000
  &key=YOUR_API_KEY

cURL

curl -L -X GET 'https://maps.googleapis.com/maps/api/timezone/json?location=39.6034810%2C-119.6822510&timestamp=1331766000&key=YOUR_API_KEY'

JSON

{
  "dstOffset": 3600,
  "rawOffset": -28800,
  "status": "OK",
  "timeZoneId": "America/Los_Angeles",
  "timeZoneName": "Pacific Daylight Time",
}

XML

<TimeZoneResponse>
 <status>OK</status>
 <raw_offset>-28800.0000000</raw_offset>
 <dst_offset>3600.0000000</dst_offset>
 <time_zone_id>America/Los_Angeles</time_zone_id>
 <time_zone_name>Pacific Daylight Time</time_zone_name>
</TimeZoneResponse>

此示例与以上两例类似，不同的是设置了语言参数。响应现在将本地化为西班牙语。

  "status": "OK",
  "timeZoneId": "America/Los_Angeles",

时区响应

对于每个有效的请求，时区都会以请求网址内指定的格式返回响应。

TimeZoneResponse

Field	Required	Type	Description
`status`	required	TimeZoneStatus	See TimeZoneStatus for more information.
`dstOffset`	optional	number	The offset for daylight-savings time in seconds. This will be zero if the time zone is not in Daylight Savings Time during the specified `timestamp`.
`errorMessage`	optional	string	Detailed information about the reasons behind the given status code. Included if status other than `Ok`.
`rawOffset`	optional	number	The offset from UTC (in seconds) for the given location. This does not take into effect daylight savings.
`timeZoneId`	optional	string	a string containing the ID of the time zone, such as "America/Los_Angeles" or "Australia/Sydney". These IDs are defined by Unicode Common Locale Data Repository (CLDR) project, and currently available in file timezone.xml. When a timezone has several IDs, the canonical one is returned. In xml responses, this is the first alias of each timezone. For example, "Asia/Calcutta" is returned, not "Asia/Kolkata".
`timeZoneName`	optional	string	The long form name of the time zone. This field will be localized if the language parameter is set. eg. `Pacific Daylight Time` or `Australian Eastern Daylight Time`.

TimeZoneStatus

The status field within the Time Zone response object contains the status of the request. The status field may contain the following values:

OK indicates that the request was successful.
INVALID_REQUEST indicates that the request was malformed.
OVER_DAILY_LIMIT indicates any of the following:
- The API key is missing or invalid.
- Billing has not been enabled on your account.
- A self-imposed usage cap has been exceeded.
- The provided method of payment is no longer valid (for example, a credit card has expired).
OVER_QUERY_LIMIT indicates the requestor has exceeded quota.
REQUEST_DENIED indicates that the API did not complete the request. Confirm that the request was sent over HTTPS instead of HTTP.
UNKNOWN_ERROR indicates an unknown error.
ZERO_RESULTS indicates that no time zone data could be found for the specified position or time. Confirm that the request is for a location on land, and not over water.

计算本地时间

给定位置的本地时间是 timestamp 参数与结果中的 dstOffset 和 rawOffset 字段之和。
