How to access the time value from rolling window?

I'm trying to get the day and hour of when high or low has occurred using Rolling window.

class RetrospectiveAsparagusMule(QCAlgorithm):

    def Initialize(self):
        self.SetStartDate(2019, 12, 31)
        self.SetEndDate(2020,6,1)
        self.SetCash(1000)
    
    for symbol in self.curr:
            
            self.eurusd = self.AddForex(symbol, Resolution.Hour).Symbol
            self.SetBenchmark(symbol)
            
            self.Consolidate(self.eurusd, timedelta(hours=4), self.HourQuoteBarHandler)
            self.window = RollingWindow[QuoteBar](60)
        
        #self.SetWarmUp(60)


def OnData(self, data):
        
        if not (self.window.IsReady):
            return
        
        for symbol in self.curr:
            price = data[symbol].Close
        
        time = {}
        
        for i in range(60):
                self.high_values.append(self.window[i].High)
                self.low_values.append(self.window[i].Low)
                time[self.window[i].High] = self.Time
                time[self.window[i].Low] = self.Time

In this case self.Time will return only the actual time of the backtest and not the value I'm looking for which is the time at which the high and low have occurred on the chart.

Is this something that can only be achieved through history request?
