[Kst] Plotting time values

[Sonic]

Is there any way to plot time values in HH.MM.SS[.mmm] format as x-axis 
for an ASCII file?

I've attached a plot file result from a real test we do at work. We are 
using a Windows based software called Easyplot for opening such files. 
it autodetects the format of the first column as time (even the 
milliseconds) and plots accordingly. Zooming operations also work fine.

Can I do anything similar with Kst? If there's no support right now, I'm 
interesting in writing one and contributing to the project. I've 
reasonably good Qt/C++ skills.
In the mean time, is there any other format for using such time data? 
Will fractional C-time (for supporting milliseconds) value work?

regards,

Syam
