Update PC time with server - C#

Question

Does anyone know how I would force the computer to update the time with the time server, you can do this manually doing: Right Click on time -> Adjust date/time -> Internet Time -> Change Settings -> and update now.

I want to write a program that incorpates that same functionality, but does it automaticly.

Any suggestions?

You do realize Windows already does this, right? It automagically synchronizes like once a week. — cHao, Dec 26 '11 at 10:13

Though I dont know why you need it, We have something similar but we actually simulate a date on client using remoting/wcf which sync with server as our rest of communication is using Remoting/WCF. Changing time on client blindly may cause some other issues with other applications running on the client box. — Surjit Samra, Dec 26 '11 at 10:41

You can write directly in the windows registry from your program, the interested key is :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
