I'm looking for a countdown timer application that persists between restarts and takes away time if the PC turns off.
For example, I'd like to be able to set an alarm for 27 hours. 3 hours later I turn my computer off for 12 hours and then turn it back on. I would then like the alarm to go off automatically (sound or popup, I don't mind) 12 hours later.
Preferably I would like to not have the timer in my taskbar, though in the tray is fine.
The main aspect of this application is it must be persistent and account for time when the application is not open. If I have to set it to start with Windows that is fine. I don't mind if the application is open-source, but it would preferably be freeware and NOT a web-app.
