/////////////// CONFIGURATION /////////////////////////////

	// Set the clock's font face:
	var myfont_face = "Verdana";

	// Set the clock's font size (in point):
	var myfont_size = "10";

	// Set the clock's font color:
	var myfont_color = "#000000";
	
	// Set the clock's background color:
	var myback_color = "#FFFFFF";

	// Set the text to display before the clock:
	var mypre_text = "(External Clock JavaScript by Mark Plachetta) - The time is: ";

	// Set the width of the clock (in pixels):
	var mywidth = 300;

	// Display the time in 24 or 12 hour time?
	// 0 = 24, 1 = 12
	var my12_hour = 1;

	// How often do you want the clock updated?
	// 0 = Never, 1 = Every Second, 2 = Every Minute
	// If you pick 0 or 2, the seconds will not be displayed
	var myupdate = 1;

	// Display the date?
	// 0 = No, 1 = Yes
	var DisplayDate = 0;
