Example

Class MyTimer: Object
    tStart, tStop, Time: Decimal;

    Public Constructor Create;
    Begin
        tStart := DateTime.Ticks64;
    End Constructor Create;

    Public Function GetTime: Decimal;
    Begin
        tStop := DateTime.Ticks64;
        Time := tStop - tStart;
        Return (Time / 1000);
    End Function GetTime;

End Class MyTimer;

The specified class enables the user to register object lifetime. The countdown starts from the moment of class object creation. Object lifetime in seconds is returned by the GetTime function.
