First off, this has nothing particular to do with splot.  It's a feature
of how time/date data is parsed in gnuplot.  The strange behaviour is
actually that Test case 1 worked, rather than that case 2 didn't. It's
clearly documented (e.g. in 'help timefmt') that you must always use a
'using' specifier if you're going to use time data.

No.  Nor is that what the error message says, is it?  It says you need a
"full using spec", not that you can't do this at all.

That's almost certainly because you're trying it in the wrong way --- I
see a request mail you sent to the list address, detected and bounced to
me, the list admin.  Please subscribe via the web page instead.
