In the current design, it seems NT just simple divide the number of bars on chart with a fixed number (depends on the bar width and font size) and draw a verticle line every a few bar so that those verticle grid lines are drawn at time points without any meaning to traders.
Please take a look at other charting software such as eSignal and Amibroker, they do a better job in terms of the vertical time grid lines.
