/***************************
*********IMPORTANT**********
****************************
USE THE FOLLOWING GLOBAL
VARIABLES TO CHANGE TARGET
TIMES FOR THE THREE CLOCKS
event1Str, event2Str, event3Str
THE TARGET TIMES ARE
REPRESENTED AS DATESTRINGS
WITH THE FOLLOWING ITEMS:
1. MONTH (SELF-
EXPLANATORY, SPELL
CORRECTLY)
2. DAY OF MONTH
3. YEAR
4. HOUR IN MILITARY TIME
5. MINUTES
6. SECONDS
PUT TOGETHER, THESE ITEMS
SHOULD LOOK LIKE
var event1Str = "February 22, 2012 15:00:00";
var event2Str = "March 22, 2012 15:00:00";
var event3Str = "March 31, 2012 15:00:00";
Place them before this script reference.
