How to set mintime in jquery datetimepicker?

DateTime

I am using jquery datetimepicker.

i am able to disable time before current time by using following code.

$("#startDate").datetimepicker({
     dayOfWeekStart: 1,
     minDate: 0,

     format: 'd/m/Y H:i',
     formatTime: 'H:i',
     formatDate: 'd/m/Y',
     startDate: currentDateTime,
     ampm: true,

 });

I am having two controls. Start date and End date.
condition:
when user select any date time, value of EndDate will be a day and half an hour ahead.
e.g. if startdate is 11-05-2016 18:00 then
endDate will be 12-05-2016 18:30 (user will not be able to select previous time wrt to endDate time i.e. disable time upto 18:00)

I have achieved above functionality but fails to disable time.
I have used moment js to format date.

What I have tried:

var jsDate = moment($("#JobDate").val(), 'DD-MM-YYYY HH:mm'); 
var minimum = function(jsDate){
       if(jsDate.getMinutes()==0){
         this.setOptions({
            minTime : jsDate.getHours()+":"+(parseInt(jsDate.getMinutes())+33),
            });
       }
       else{
         this.setOptions({
            minTime : (parseInt(jsDate.getHours())+1)+":00",
            });
         }
     };

$("#EndDate").datetimepicker({
     startDate:datetime1,
     onChangeDateTime:minimum,
     onShow:minimum,
 });
var dt = new Date(jsDate.add(1,'days'));
 $("#startDate").val(dt.toString("DD-MM-YYYY HH:mm");

from jquery datetime tutorial i tried above code but it's not working.

if I'm uses minTime : 0 then it is disabling previous time wrt to current time. and that is perfactly fine in the case of startDate. When i try to disable previous time wrt to specific time(i.e.disable time from startDate's selected time for EndDate) as shown above, its not working.

What's wrong with the code?
