Alarm Clock Application is an useful utility for your desktop. Set Alarm Clock to wake you up whenever you want. You can combine any of a week's days and choose the time for the alarm clock to start(in hours, minutes and even seconds). Check the snooze option if you want to lay in bed for a few more minutes. You also have the option to set a single alarm.
After you check your settings, the Alarm Clock Application will reside in system tray.
