Highest high Number or Time

 
 HH =  iHigh(Symbol(), TimeFrame, iHighest(NULL,0,MODE_HIGH,NoOfBars,StartingBar));
 LL =  iLow(Symbol(), TimeFrame, iLowest(NULL,0, MODE_LOW,NoOfBars,StartingBar));   
Please, is it possible to use a formula to find out which bar had highest high and lowest low or the time when it was?
 
int highest_bar_index = iHighest(NULL,0,MODE_HIGH,NoOfBars,StartingBar)
datetime highest_bar_time = iTime(NULL,0,highest_bar_index)
