I am trying to calculate the time taken to send email message and time taken to receive email message. i am using EWS in my program , I set streaming notification to receive call back when a new mail reaches reciptent mailbox .

once received notification i bind the Itemevent with ews service , i checked the item properties DateTimeCreated, DateTimeSent, DateTimeReceived.All these properties are of DateTime object.

I checked DateTimeSent milisecond is always 0, whereas DateTimeCreated, DateTimeReceived has millisecond value.

I couldnot figure out why DateTimeSent millisecond is always 0 everytime. if i want to claulate time taken from send to receive what should i do.

DateTimeReceived - Datetimesent is the actual time taken to send and receive the message?

or what is the correct way to calculate time taken to send and receive the message?

Do you mean that you have a normal date value, but its precision is to the second, rather than the millisecond? – Llama
Precision set Milliseconds but still cant find millisecond in DateTimeSent – jayrag pareek

set DateTimePrecision as Milliseconds

   ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
    service.Credentials = new WebCredentials(username, password);
    service.Url = new Uri(ConfigSettings.EmailConnectionUrl);
    service.DateTimePrecision = DateTimePrecision.Milliseconds;

how about actually measuring the Timespan? so for example showing total milliseconds but you could change that to suit

var result=((TimeSpan)(DateTimeReceived  - DateTimeSent )).TotalMilliseconds.ToString("#,##0.00") + "ms";

In the EWS Managed API the ExchangeService class has a precision property that you need to set before you make any calls see https://msdn.microsoft.com/en-us/library/microsoft.exchange.webservices.data.exchangeservice.datetimeprecision(v=exchg.80).aspx
