Question

how to set local time on windows mobile device

Asked by: bmutch

we are creatting a text file with the current time and date from a PC and sending it to the remote device and setting the time. The line of text in the file will be local time on the PC and I need to set the local time on the device from it.

For instance the line of text might be:
200909031114     ' for 9/3/09 at 11:14 AM
I need to set the device time from this.
I have the code below but it sets the GMT time...

thanks.

...   // c#
 
 
        [DllImport("coredll.dll", EntryPoint = "SetSystemTime",
        SetLastError = true)]
        public extern static bool WinCESetSystemTime(ref SystemTime st);
 
public struct SystemTime
        {
            public ushort Year;
            public ushort Month;
            public ushort DayOfWeek;
            public ushort Day;
            public ushort Hour;
            public ushort Minute;
            public ushort Second;
            public ushort Millisecond;
        };
 
strFileTime = ReadLineFromFile(TimeFile);  // strFileTime = "200909031114"
            dt = new DateTime(Convert.ToInt32(strFileTime.Substring(0, 4)), Convert.ToInt32(strFileTime.Substring(4, 2)), Convert.ToInt32(strFileTime.Substring(6, 2)), Convert.ToInt32(strFileTime.Substring(8, 2)), Convert.ToInt32(strFileTime.Substring(10, 2)),0);
 
SystemTime st = new SystemTime();
 
            st.Year = (ushort)dt.Year;
            st.Month = (ushort)dt.Month;
            st.Day = (ushort)dt.Day;
            st.DayOfWeek = (ushort)dt.DayOfWeek;
            st.Hour = (ushort)dt.Hour; 
            st.Minute = (ushort)dt.Minute;
 
bool result = WinCESetSystemTime(ref st);
