Use the SetSystemTime api call.

E.g.  To set time to 20 May 1998, 10:30 a.m.

procedure SetNewSystemTime;
var
  SysTime: TSystemTime;
begin
  FillChar(SysTime, SizeOf(TSystemTime), 0);
  SysTime.wYear := 1998;
  SysTime.wMonth := 5;
  SysTime.wDay := 20;
  SysTime.wHour := 8;
  SysTime.wMinute := 30;
  SetSystemTime(SysTime);
end;


Note:  The hour will be 2 more than you specify on Win 95.  (NT???)

Thank you

it works fine but, a have a small problem with timezones. the procedure that you wrote will set the time as if the timezone was GMT. Do you know how to see that timezone that currently is in use ?

Ah, that would explain why I need to -2 for hour!!

To get current timezone bias, use GetTimeZoneInformation.

E.g.
var
  MinutesDiff: Integer;
  TZInfo: TTimeZoneInformation;
begin
  GetTimeZoneInformation(TZInfo);
  MinutesDiff := TZInfo.Bias;
end;

In my case, MinutesDiff = -120 (i.e. 2 hrs behind).

P.S.  If you don't want do the TimeZone thing, use SetLocalTime instead of SetSystemTime.
