Countdown Timer

The Countdown timer was written in January 2012 for the Chesapeake Curling Club. It's intended purpose is to allow curling rinks on the ice to monitor their progress and keep games moving. The recommended use is that when the screen turns red, teams are allowed to finish the end they are playing, but not to start another. As a warning, the screen (optionally) turns yellow at a predetermined time before the timer runs out. All times, and font size, are configurable at run time, with the ability to choose between counting down to zero and up to a specific time limit such as 1 hour 50 minutes. Defaults are easily changed with the text editor (notepad?) of your choice.

You may right click on this link to save it locally, or just click it and run it from the web.

The code is offered "as is" at no charge. Feel free to modify it with the text editor (notepad?) of your choice. Default values are all specified in the first few (~20) lines of code. Dick Bemis, who requested the program, has successfully changed the defaults for the Chesapeake Curling Club.

Technical stuff: The code does not have a <!DOCTYPE html> statement before the opening <html> tag. This omission violates IETF standards, but allows it to run completely disconnected from the internet. It is written entirely in javascript, surrounded by a few html tags, and has been tested on multiple versions of Windows, Linux (Ubuntu), Mac OS X, and the iPad tablet. It is a web (html) application that also runs locally on your PC (or Mac or Linux or whatever) computer. The Firefox, Internet Explorer, and Safari web browsers have all been successfully tested. Most reasonably modern browsers will have no trouble at all. Your mileage may vary.
