Solicitudes y respuestas de zona horaria

Zona horaria

Las solicitudes a la API de Time Zone se construyen como una cadena de URL. La API muestra la zona horaria para un punto de la Tierra, especificada mediante un par de latitud y longitud. Ten en cuenta que los datos de zona horaria pueden no estar disponibles para ubicaciones que se encuentran sobre el agua, como océanos o mares.

Una solicitud de zona horaria tiene el siguiente formato:

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

donde outputFormat puede ser cualquiera de los siguientes valores:

  • json (recomendado) indica el formato de salida en JavaScript Object Notation (JSON), o
  • xml, indica el formato de salida en XML, agrupado en un nodo <TimeZoneResponse>.

Nota: Las URLs deben estar codificadas correctamente para ser válidas y tienen una limitación de 16,384 caracteres para todos los servicios web. Debes tener en cuenta este límite cuando construyas tus URLs. Ten en cuenta que los diferentes navegadores, proxies y servidores también pueden tener límites de caracteres diferentes para las direcciones URL.

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.

Respuestas de zona horaria

Para cada solicitud válida, la zona horaria muestra una respuesta en el formato indicado en la URL de la solicitud.

TimeZoneResponse

FieldRequiredTypeDescription
requiredTimeZoneStatus See TimeZoneStatus for more information.
optionalnumber

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.

optionalstring

Detailed information about the reasons behind the given status code. Included if status other than Ok.

optionalnumber

The offset from UTC (in seconds) for the given location. This does not take into effect daylight savings.

optionalstring

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".

optionalstring

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.

Calculando la hora local

La hora local de una ubicación determinada es la suma del parámetro timestamp y de los campos dstOffset y rawOffset del resultado.
