I am trying to fill an array/list with values from a time subtraction. I have start time in this format “09.00 AM” and End time in the same format ex: “06.00 PM”, both times are coming from two drop downs (values from 9 am to 9 pm with hourly increments) which are actually jquery time picker controls. This is what I am trying to do.. after user selects both times, I want to populate an array/list with individual “hour” mark values that fall between the two selected time values. For ex: selecting 9 am and 12 pm should give me values { “10.00 AM”, “11.00 AM”}.. selecting 10 AM to 4 PM should give me {“11.00 AM”, “12.00 PM”, “01.00 PM”, “02.00 PM”, “03.00 PM”}.. 

var FirstTime = container.find('#1time').val();
var SecondTime = container.find('#2time').val(); 

var busyTimes = [];
busyTimes =  getBusyTimes(FirstTime , SecondTime);

Function js:

function getBusyTimes(first, second) {
    var f = first.split(' '), s = second.split(' ');
    if (first == '12.00 AM') f[0] = '0';
    if (first == '12.00 PM') f[1] = 'AM';
    if (second == '12.00 AM') s[0] = '24';
    if (second == '12.00 PM') s[1] = 'AM';
    f[0] = parseInt(f[0], 10) + (f[1] == 'PM' ? 12 : 0);
    s[0] = parseInt(s[0], 10) + (s[1] == 'PM' ? 12 : 0);
    int i = s[0] - f[0];
    // I have difference in hours in "i"
    //From here, I want to make use of value 'i' -- calculate in between   
    // hourly values and return the array back to 
    // original function above.
}

    I have not tested this but it should work for what you are trying to do and it should operate faster than the calculations you are trying to do.

    function getBusyTimes(first, second){
var timeList = ['12:00 AM','1:00 AM','2:00 AM','3:00 AM']; // finish this list
var firstid  = timeList.indexOf(first);
var secondid = timeList.indexOf(second);
var result = new Array();
for(var i=firstid; i<=secondid; i++ ){
    result.push(timeList[i]);
}
return result;
}
