Title: How to handle system time change using Delphi code
If you need to react when system date time has changed you can handle the WM_TimeChange Windows message.
Here's a sample code:
~~~~~~~~~~~~~~~~~~~~~~~~~
type
TForm1 = class(TForm)
private
procedure WMTimeChange(var Msg: TMessage) ; message WM_TIMECHANGE;
end;
var
Form1: TForm1;
implementation
{$R *.DFM}
procedure TForm1.WMTimeChange(var Msg: TMessage) ;
begin
inherited;
ShowMessage('Date/Time has changed!') ;
end;
~~~~~~~~~~~~~~~~~~~~~~~~~
Note: the "Handling Windows Messages the Delphi way" article has more info on Windows message handling from Delphi code.
