The auto-axis routines don't go out that far. We will have to add that range in a subsequent version. In the meantime you can just set a couple of axis properties, in bold.
xAxis = New TimeAxis(pTransform)
xAxis.AxisMinorNthTick = 1
xAxis.AxisMinorTicksPerMajor = 10
This will draw the time axis OK initially. But if you are zooming the axis, starting at this point, when you return to the original scale the axis will revert to its old form. We will have to fix the auto-scale routine internally before zooming will work across such a wide range. Contact email@example.com in couple of days for an updated DLL.
