You can use timeit.exe from the Windows Server 2003 Resource Kit.

Syntax:

timeit [-f FileName] [-a] [-c] [-i] [-d] [-s] [-t] [-k KeyName | -r KeyName] 
[-m Mask] [Command]

-f FileName  
Specifies the name of the database file where TimeIt keeps a history of 
previous timings. The default file name is .\Timeit.dat

-k KeyName
Specifies the keyname to use for this timing run.

-r KeyName
Specifies the key name to remove from the database. If the key name is 
followed by a comma and a number, the slowest time (positive number) or
the fastest time (negative number) for that key name will be removed.

-a
Specifies that TimeIt should display average of all timings for the 
specified key name.

Write a C program using the GetProcessTimes function, you could find its documentation in: http://msdn.microsoft.com/en-us/library/ms683223%28VS.85%29.aspx.

In the examples of the book "Windows System Programming" comes a program that use that function to retrieve exactly what you need(Elapsed, Kernel, User times). The program is call "timep.exe" and it can be found in the runX subdirectories (the X comes from the version of Visual Studio used in the compilation) inside the zipped examples archive. Here is the author page from where you could download that archive http://www.jmhartsoftware.com/, of course the source code is also there so you could see exactly how timep.exe works.
