Web 部署在 Azure 上的应用程序未返回 UTC 日期时间

Question

I have deployed a backend microservice in .net core 3 on Azure and am returning a list of datetime values which i have converted to UTC using ToUniversalTime() method. For some reason the datetimes returned are not converted to UTC and are the same values stored in db. It works well when i run it locally.

Answer 1

By default, Azure Web Apps run in UTC timezone. So for the application, a local time that is read from the database is interpreted to be UTC, hence calling ToUniversalTime does not change the value. You can specify the timezone for the Web App using the WEBSITE_TIME_ZONE setting as described here: https://www.jasongaylord.com/blog/tip-changing-an-azure-app-service-time-zone
