Help How to get server date in c#

If the server is a database server, and your clients all access that database, then you should be able to get the time from the database, e.g. GETDATE() in SQL Server. Otherwise you'll want UTC. I don't think anything else will be guaranteed to be what you want.

At my current job I access many servers across the U.S., possibly around the world. For consistency, they are all set to "U.S. Central time" (UTC-6:00). But my settings specify Arizona (UTC-7:00) so I see that. Another user might see yet another time.

So, you need to use UTC or have all your clients ask a common process (the database service for instance).

These answers are partial and unclear.
One suggestion was to set up a web service that allows the server to send out UTC time. This is the best answer, but you should note that if you have two servers they need to stay in sync. All servers get their time updated/maintained from time servers, typically Microsoft or other NTP servers. Time should always be updated on server to stay in sync, you can not expect your server to be the time standard for the world. So that needs to come from the network or NTP devices that manage that from an atomic clock.

You app could then get the needed time from your server when you write records. There is no easy technique for getting server side time from a code behind page. That is why the service was suggested. The web service would pull the time from the server and send it back to the client in the call to the web service. Then you could use that servers time to update, but note that the time returned is not going to keep ticking. You will need to keep an internal clock if your process runs long before you write your record to your database.

Example, you query your web service for the UTC time and it returns 12:01:44:025, twelve hours, 1 minute, 44 seconds, 25 milliseconds. If your processing takes say :200 milliseconds, you would want to increase your milliseconds to :225 before writing the record to your database. The timestamp value you get back from your web service will not keep ticking up 200 seconds while you are processing.

So if that level of accuracy is important you can manage it. By getting another timestamp from the local PC when you receive the timestamp from the server, then subtracting that from the current time just prior to storing your processed data, but first adding that difference to the server timestamp that was returned from the service.

Sounds like a lot of over head. But its not that difficult to implement, other than the web service if you are not familiar with it.

String currDateTime = System.DateTime.Now.ToString();

Try the below code.Write the code in Load method,
textBox1.Text = DateTime.Now.ToShortDateString();
