Count-Down Timer

Count-Down Timer is a simple application for displaying the time-remaining for an event, such as for:

cooking,
chess playing tournaments,
debate speech timing,
governing floor-time at public speaking events,
paper presentations,
etc.

The numbers appear large enough to be seen at a distance, or the display can be shrunk into the corner of a presentation screen. The time-remaining display changes color, as a warning, near end of the duration.

The display also shows elapsed time, and has a pause/resume button. This timer application is a simple stand-alone executable that can be placed on any computer, and does not require an internet connection to use it.

It can be used to count-down time for events lasting less than one minute, or for durations lasting hours, days, or up to a year.

Features:

Counts backwards down to zero. (Shows Time-remaining)
A smaller display simultaneously shows total elapsed time.
Allows full-screen display (to see from a distance), or small (for viewing along side other windows). Just re-size the window, and the time-display scales accordingly (unlike most other timer applications).
When it first opens, it shows a dialog window open for setting the duration, and other settings before beginning.
Once set up, the time display occupies the majority of the window. There is a small button to Start, Pause, and Reset the timer, as well as a button to go back to the settings window, and to exit.
The time-display turns Yellow when getting close to timing-out. You can set this transition time on the set-up/options window. When the time-duration expires, the display blinks several times and changes Red, to grab your attention.
It accepts time in minutes, as well as Days:Hours:Minutes:Seconds, and various subsets there of.
You can set the time of transition between warning-colors.
The display automatically formats itself for reasonable display of both short times and long times. In other words, it doesn't waste display space showing days and hours, if you are timing a 3-minute egg. But it does display hours or days if you have it set for a multi-hour or multi-day duration.
It is programmed in C-language, so everyone can extend it and integrate easily with other things, and so it can run on any machine without installing extra stuff. Based on Open Tool Kit (OTK).
It runs without needing an internet connection or web browser.
Simple, yet versatile. Uses very little machine resources or CPU time.
Supports an option to run an arbitrary command or script when the time expires. Can be used to play a sound file, or close stage curtains, etc..

Usage:

Fairly self explanatory:

Set the duration. Click OK.
Press Start when ready to begin count-down.

You can type the duration in straight minutes, or in Minutes:Seconds, or Hours:Minutes:Seconds, or Days:Hours:Minutes:Seconds.
