hi expert

i write sample application for setting system time and system date programatically

my code contains :

step 1) I import the kernel.dll for GetSystemTime && SetSystemTime

Quote:

quote:[DllImport("kernel32.dll")]

Quote:

static extern bool SetSystemTime(ref SYSTEMTIME time);
[DllImport("kernel32.dll")]
static extern void GetSystemTime(out SYSTEMTIME lpSystemTime);

i write a structure such as follow

step 2 ) i write following structre

Quote:

quote:public struct SYSTEMTIME

Quote:

        {
            public short year;
            public short month;
            public short dayOfWeek;
            public short day;
            public short hour;
            public short minute;
            public short second;
            public short milliseconds;
        }

step 3) and finally i write in button1_click

Quote:

quote: try

Quote:

            {

                SYSTEMTIME time= new SYSTEMTIME();

                GetSystemTime(out time);
                time.hour = 12;
                time.year = 2001;
                SetSystemTime(ref time);
                MessageBox.Show("system time and date hase been changed successfully");
            }
            catch (Exception ex)
            {

                MessageBox.Show(ex.Message);
            }

and now my questions

1) as you see i set the hour to 12 but after clicking the button the system time seted to 4 PM , why?

2 )how can i set the year to 1386 ? in fact in above code where i set the year less than 2000 my code become ignore , why?

regards

Could it be that your time zone is what offsets the time? Try setting your zone to GMT and see if you get the same result.
