You can create a Calendar object with the values from your DatePicker and TimePicker:

Calendar calendar = Calendar.getInstance();
calendar.set(datePicker.getYear(), datePicker.getMonth(), datePicker.getDayOfMonth(), 
             timePicker.getCurrentHour(), timePicker.getCurrentMinute(), 0);
long startTime = calendar.getTimeInMillis();
