SetSystemTime

[MDB]

Hello all, I am having problems with SetSystemTime. For some reason, my
ppc2003 device is not adjusting for DST (time behind by one hour). Here is
how I am setting it with the UTC time being passed to the function, should I
be doing this differently?

[DllImport("coredll.dll")]
private extern static bool SetSystemTime(ref SYSTEMTIME lpSystemTime);

public static void SyncSystemTime(string strDateTime)
{
try
{
// Set the clock ahead one hour
SYSTEMTIME st = new SYSTEMTIME();
DateTime temp = Convert.ToDateTime(strDateTime);
st.wYear = (ushort)temp.Year;
st.wMonth = (ushort)temp.Month;
st.wDayOfWeek = (ushort)temp.DayOfWeek;
st.wDay = (ushort)temp.Day;
st.wHour = (ushort)temp.Hour;
st.wMinute = (ushort)temp.Minute;
st.wSecond = (ushort)temp.Second;
st.wMilliseconds = (ushort)temp.Millisecond;
if(!SetSystemTime(ref st))
{
myapp.Classes.Errors.LogNonExceptionError("Time not synced - " +
strDateTime,"Functions","SyncSystemTime","");
}

}
catch(Exception exc)
{
myapp.Classes.Errors.LogException(exc,"Functions","SyncSystemTime","");
}
}

SetSystemTime() is setting the GMT time, *not* the local time of the device!
SetLocalTime() would be used to set the local time that the device
uses/displays.

If you are saying that, despite setting the correct DST value, the local
time reported is wrong, then I'd guess that you haven't set the timezone and
DST adjustment flag correctly. Check the Control Panel.

Yes I know it is the GMT/UTC and yes the timezone is set correctly. What I
have not been able to check is the DST adjustment flag. Where is this found
in PPC2003? I can not seem to find it.

To check if it turn on (it should be on) see registry value:
HKLM/Software/Microsoft/Clock/HomeDST

You can force it on or off by calling SetDaylightTime().
