Change system date/time using .NET class library

Question

Hi all I am new to GotDotNet. I have been working with .NET framework using VB C# and MC++ for past one year. I need to change the system date/time from one of my applications written in C#. Can anybody please tell how it can be achieved? Thanks in advance for help...! PS. I have checked that Microsoft.VisualBasic.DateString property can be used to achieve this effect but I do not want to use VB runtime.

You mean you want to modify the time on the System? On the machine that is running? [DllImport(kernel32.dll)] static extern bool SetLocalTime(ref SYSTEMTIME time); [StructLayoutAttribute(LayoutKind.Sequential)] private struct SYSTEMTIME { public short year; public short month; public short dayOfWeek; public short day; public short hour; public short minute; public short second; public short milliseconds; } SYSTEMTIME st; st.year = ... st.month = ... st.dayOfWeek =... st.day = ... st.hour = ... st.minute = ... st.second = ... st.milliseconds = ... SetLocalTime(ref st); I believe that will work.
