I don't think you can, at least not without hacking the source code.
Currently I don't have 1.0 source code around, but assuming this part
hasn't changed much, you'd have to look in rrd_graph.c function
vertical_grid , look for strftime (end of the function).

Is there no way, at all, for you to get accurate time?
Perhaps add a chip to your computer that keeps time, or perhaps
using a time server on the internet?
