I downloaded all daily data from Yahoo.
When I pull into a chart, I realized that some stock has time stamp recorded correctly at 16:00PM. However, for some other stock, the time stamp is actually 00:00AM and the day shifted by 1 day to the next. I understand that the downloaded daily data from Yahoo does not have time stamp. Therefore, some time stamping must be done in NT.
This causes problem for my programs because I need correct day information.

I attach the chart for AAPL which has proper time stamp and PANL which has wrong time stamp. Notice that the price jump in PANL actually occurred on March 16. However, the chart shows the price jump on March 17.
