Javascript - In time and out time difference

	inTimeHHMM 			= inTime.split(":");
	outTimeHHMM 		= outTime.split(":");
	var today 			= new Date();
	var dateInTime 		= new Date(today.getFullYear(), today.getMonth(), today.getDate(), inTimeHHMM[0], inTimeHHMM[1], 0);
	var dateOutTime 	= new Date(today.getFullYear(), today.getMonth(), today.getDate(), outTimeHHMM[0], outTimeHHMM[1], 0);
	if(dateInTime<=dateOutTime){
	}else{
		dateOutTime.setDate(dateOutTime.getDate() + 1);
	}
	var diff =(dateOutTime.getTime() - dateInTime.getTime()) / 1000;
	diff /= 60;
	workingMinutes = Math.abs(Math.round(diff));

Daterangepicker set min time

Date.prototype.addHours = function(h) {    
   this.setTime(this.getTime() + (h*60*60*1000)); 
   return this;   
}
var currDate = new Date().addHours(5); // 5 is the hours
 
$('#fromDate').daterangepicker({
 minDate: currDate,
 timePicker: true,  
 singleDatePicker: true, 
 timePickerIncrement: 1,
 format: 'DD/MM/YYYY hh:mm A'
});
