I am using a day based time scale on x-axis. Without further action the
days are aligned at 00:00 as depicted here... (please use a mono-space
font to view the following sketches)

   |-----|-----|
  Mon   Tue   Wed

I want the whole days from 00:00 to 24:00 marked with the day name, that
the x-tics labels are centered on the day

   |-----|-----|
     Mon   Tue

So I applied an offset argument to the command. My actual commands are

  set xdata time
  set format x "%a"
  set xtics 86400
  set mxtics 8
  set xtics offset first 86400/2

with the following result

   |-----|-----|
     Mon   Tue   Wed

You can see that the "Wed" isn't necessary and even spoils the diagram.

This is a re-post from a few years ago where no one could point me to
a solution; so if that's something not possible to achieve with gnuplot
I'd appreciate to get a negative confirmation.

My current workaround is a hack; I postprocess the png file that gnuplot
creates with the imagemagic tools to graphically clear that part of the
image. I'd like to avoid that hack and prefer a gnuplot solution.

Thanks for any hints.
