时区
Time Zone API 请求以网址字符串的形式构建。API 返回时区 地球上某个点的数据,由纬度/经度对指定。请注意,时区 数据可能无法获得水上位置(如大洋或海上)的数据。
时区请求采用以下形式:
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 对象表示法 (JSON);或xml
,表示以 XML 格式输出,并封装在<TimeZoneResponse>
节点。
注意:网址必须 编码正确 才有效,且对于所有网络服务,均不得超过 16384 个字符。 请在构建网址时注意这一限制。请注意,不同的浏览器 代理和服务器也可能有不同的网址字符数限制。
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 thelocation
.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 theAccept-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。
以下查询针对美国内华达州执行时区请求。时间戳 设置为 2012 年 3 月 8 日。

时区响应
对于每个有效请求,时区都会在 指定的格式。
TimeZoneResponse
Field | Required | Type | Description |
---|---|---|---|
| required | TimeZoneStatus | See TimeZoneStatus for more information. |
| 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 |
| optional | string |
Detailed information about the reasons behind the given status code.
Included if status other than |
| optional | number | The offset from UTC (in seconds) for the given location. This does not take into effect daylight savings. |
| 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". |
| optional | string |
The long form name of the time zone. This field will be localized if
the language parameter is set. eg.
|
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.
