如何使用CSOM模型获取SharePoint服务器日期时间？

Question

I'm creating a service that will notify people about new tasks in SharePoint. For this I have to somehow get it's server datetime due to a huge desynchronisation gaps in time value when comparing it to datetime.now result.

Answer 1

SharePoint store datetime as UTC time, so try to use TimeZone.UTCToLocalTime 。

var localTime = context.Web.RegionalSettings.TimeZone.UTCToLocalTime((DateTime)listItem.FieldValues["Created"]);
                context.ExecuteQuery();
                Console.WriteLine(localTime.Value);
