People use gnuplot for an amazing variety of applications.
I am continually surprised at where I come across it,
and at what people tell me they use it for.
Probably no one person has ever made use of all the options, settings,
features, and quirks that have accummulated in the gnuplot code.

The point I am trying to make is that you should not assume that
what you are trying to do lies on some well-trodden path from which
many previous users have found and removed all the obstacles and bugs.
In this case you have tripped over a behavior that has been there
for the last 10 years, when the "offset" option was added for "set tics".
  
Is it a bug?   yeah
Is it fixable? probably
Are you really the first one to hit it?
I don't know, but I see no previous bug reports on the tracker.
Either nobody tried this or they found a work-around and didn't
bother to report it.  That doesn't match the profile I would
expect for a "severe" bug - more like an unexpected restriction
in a little-used feature.

Anyhow, it's got a tracker number now, and will probably get
a fix in due time:
