[ROOT] Time axis with TGraph .....

Dear ROOTers,

I am interested to apply the time axis. One example uses the Histogram.
http://root.cern.ch/root/HowtoTimeAxis.html

I just could not follow the example if change to TGraph.
I wanted to make an offset at Feb. 15, 2003. Maybe my range of the 
coordinates are too high.

For example after converting via mktime, values of the XTime values are of 
the order of 10 to the 8 or so (1058855025 seconds). How do we deal with 
this large number for it to be plotted in the time axis? Do we need to 
subtract with the offset?

     (i.e., 1058855025 seconds - Feb. 15, 2003 in secondds) ?


Thank you?
