Fiware-IDAS：TimeInstant属性 [英] Fiware - IDAS: TimeInstant attribute

问题描述

我正在使用MQTT Ultralight代理。我已经看到，当代理向上下文代理注册与设备相关的实体时，代理会将 TimeInstant属性添加到该实体。此属性似乎在UTC + 0上。

I’m using the MQTT Ultralight agent. I have seen that when the agent registers into the context broker an entity related to a device, the agent adds to that entity the "TimeInstant" attribute. This attribute seems to be on UTC+0.

我想使用UTC +1。我尝试在注册设备时修改设备的 TimeZone，但似乎不起作用，因为时间仍然是UTC + 0。下面是一个示例：

I would like to work with UTC +1. I tried modifying the device’s "TimeZone" when registering it, but seems that this doesn’t work, because the time continues to be on UTC+0. Here an example:

curl -X POST 172.21.0.23:8090/iot/devices \
-i  \
-H "Content-Type: application/json" \
-H "Fiware-Service: red_entrada_4" \
-H "Fiware-ServicePath: /Prueba" \
-d '{
"devices":[
{
    "device_id": "AC_2", 
    "entity_name":"disp_entrada:AC_2",
    "protocol":"PDI-IoTA-MQTT-UltraLight", 
    "entity_type": "disp_entrada", 
    "timezone": "Europe/Madrid" 
}
]}'

有没有办法修改 TimeInstant属性的默认值，以便

Is there any way of modifying the default value of the "TimeInstant" attribute, in order to work with a specific UTC?

推荐答案

此字段是作为将来的功能引入的，如文档中所述，它是今天不使用。这就是为什么¡您目前无法更改它的原因。

This field was introduced as a future capability and, as it is said in the documentation, it is not in use today. This is the reason why ¡you are not able to change it at present.
