function strToDate(s){				 
	var big = s.split(" ");	
	var small = big[1].split(":");
	var MMddyyyy = big[0].split("-");
	var HH, mm;
	if (big[2].toUpperCase() == "PM"){
			HH = parseInt(small[0]) + 12;
	}else{
			HH = parseInt(small[0]);
	}
	mm = small[1];
	return new Date(MMddyyyy[2], MMddyyyy[0], MMddyyyy[1], HH, mm, 0, 0);			
}

var d1 = strToDate(str1);
var d2 = strToDate(str2);
