Acute Softwares TimerPRO

Records time elapsed in a number of ways on Win9x/NT.
It has three main timing modes:
Manual Mode (Acts as a standard stopwatch);
Timer Mode (count for a fixed amount of time...like an egg timer);
Alarm Clock Mode (timer will count until a preset time of day).
You can set alarms in either Timer or Alarm Clock mode, and each running timer can play a WAV file, pop a window, or run a program when it has finished. Timers can auto restart
