Application Insights REST API - 日光节省时间问题 [英] Application Insights REST API - Day light savings time issue

问题描述

您好，

我正在使用Application Insights REST API来提取遥测数据。

如何在AppInsights中处理夏令时？
$
我可以在2019年3月10日凌晨2点进行夏令时，在凌晨2点到凌晨3点之间看到数据中的时间戳值。

How is daylight savings handled in AppInsights?
I can see the timestamp values in the data between 2 AM and 3 AM UTC when daylight savings was done at 2 AM on 10th March 2019.

Wnat配置我的应用程序相应地从AppInsights API获取数据。

Hina！ 感谢您使用Application Insights。

Hi, Hina!  Thank you for using Application Insights.

Application Insights默认使用UTC，UTC不会因
夏令时。 这就解释了为什么您会在凌晨2点到凌晨3点之间看到数据。 然后可以将UTC转换为当地时间：

Application Insights uses UTC by default, and UTC does not change for Daylight Saving Time.  This explains why you would see data between 2 AM and 3 AM UTC.  UTC can then be converted into local time:

requests
    | where timestamp > ago(30d) and client_City == "Redmond"
    | summarize clients = dcount(client_IP) 
        by tod_UTC=bin(timestamp % 1d, 1h), resultCode
    | extend local_hour = (tod_UTC - 8h) % 24h
