How to get the time stamp base on the index of Bar?

[LadGta2018]

For example, I would like to know when the 20th bar started. it should return a time, like: 9:30am.

Could you show me a code sample? thanks

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
base.OnRender(chartControl, chartScale);
// loop through only the rendered bars on the chart
for(int barIndex = ChartBars.FromIndex; barIndex <= ChartBars.ToIndex; barIndex++)
{
// get the time stamp at the selected bar index value
DateTime timeValue = Bars.GetTime(barIndex);
Print("Bar #" + barIndex + " time stamp is " + timeValue);
}
}
