You need to give the "%a" to RRDtool so it can use it.

This instructs RRDtool to print "Sat" each time.  Change "Sat"
into "%a" (in case you display several days) or into "%H" (for
displaying hours) or another formatter from the strftime manual page.

You have, correctly, used "3600" as your resolution.  If you want
the label directly under the major grid line (for instance for time)
you need to set it to "0".

cheers,
Alex
