Delphi Using Data:
Setting the System Time in Delphi
Posted 13 years ago on 2/26/2008 and updated 5/5/2008
Take Away: SetSystemTime Example


Setting the system time in Windows 95/NT is rather simple. It requires a variable of type TSystemTime, which is a record that contains values for the date and the time. After filling the values in TSystemTime, pass it into SetSystemTime and Windows will update the system clock.

Delphi provides a function that simplifies the process of setting the values in TSystemTime. The function is DateTimeToSystemTime and takes two parameters, a Delphi TDateTime and a TSystemTime variable. The function then converts the TDateTime value to a TSystemTime and returns it in the TSystemTime variable.

Here is an example of setting the system time to the value types into an Edit Box:

procedure TForm1.Button1Click(Sender: TObject); 
   sysTime : TSystemTime;
   DateTimeToSystemTime(StrToDateTime(Edit1.Text), sysTime);
