Answer 1

嘗試GetProcessTimes功能

{$APPTYPE CONSOLE} 

{$R *.res} 

uses 
    Windows, 
    SysUtils; 

function FileTime2DateTime(FileTime: TFileTime): TDateTime; //Convert then FileTime to TDatetime format 
var 
    LocalTime: TFileTime; 
    DOSTime : Integer; 
begin 
    FileTimeToLocalFileTime(FileTime, LocalTime); 
    FileTimeToDosDateTime(LocalTime, LongRec(DOSTime).Hi, LongRec(DOSTime).Lo); 
    Result := FileDateToDateTime(DOSTime); 
end; 

Var 
    lpCreationTime, lpExitTime, lpKernelTime, lpUserTime: TFileTime; 

begin 
    try 
    GetProcessTimes(GetCurrentProcess,lpCreationTime, lpExitTime, lpKernelTime, lpUserTime); 
    Sleep(1000); //do something 

    Writeln(Format('Running Time %s',[FormatDateTime('hh:nn:ss.zzz',Now-FileTime2DateTime(lpCreationTime))])); 
    except 
    on E: Exception do 
     Writeln(E.ClassName, ': ', E.Message); 
    end; 
    Readln; 
end.
