529978 Simple timer countdown

Simple countdown script - modifiable - sesson/cookie based. A user visits our page and it says something along the lines of "Today only! $10 Off!" Then "Sale Ends: " Timer Placed Here (1 Hour, 22 Minutes, 59 Seconds, 10 Milliseconds) Time/Date format should be modifiable. 1) If we want to change from 1 hour and 22 minutes, to just 22 minutes, it should not display the hour section at all. Good: ( 22 Minutes, 59 Seconds, 10 Milliseconds ) Bad: (0 Hour, 22 Minutes, 59 Seconds, 10 Milliseconds) 2) Different time display mods. Example: ( 22 Minutes, 59 Seconds, 10 Milliseconds ) ( 22:59:10 ) ( 22:59) (Doesn't show milliseconds if that's what we select) 3) Colors for numbers and background. Example: Red numbers, white background Red numbers, black background Black numbers, white background etc Session/Cookie based: 1 user comes to site, sees timer counting down from say for example 22 minutes. Comes back 10 minutes later, times should now be at 12 minutes. If timer gets to 0, when the user comes back, it should disappear. Different styling examples: [login to view URL] [login to view URL] More simple ones with basic font/text will also work. Also note we're running on WordPress - so not sure exactly how to insert it into pages.... Skills: HTML, JavaScript, PHP
