Description: In javascript whenever you write new Date() it shows the current date in standard format with current day,date,time and GMT.You can have your own format.

          getHours() shows hours of specified date.
          getMinutes()  shows minutes of specified date.
          getSeconds()  shows seconds of specified date.

Input minutes which you want to add into current time.parseInt() is used to convert the value in integer. Simple add minutes into the current minutes by writing var newMins = parseInt(minutes) + parseInt(mins);
