I know how to get stock data from Yahoo! finance.

However, does anyone know how to grab this data at a certain time of the day? What I means is this: let's say it's 8pm eastern time, and I need to grab the data for 2:30pm eastern time. I know they have this type of historical data, but not a clue how to get it for that prior time period.

Any help is appreciated....
