gnuplot all points y value undefined

I just dont get it. What I am doing wrong. This data file: test.csv

1981-12-12-12:12:12,12
1981-12-12-13:12:12,15
1981-12-12-14:12:12,18

And this gnuplot script:

set datafile separator ','
set xdata time
set timefmt '%Y-%m-%d-%H:%M:%S'
set xrange ["1981-12-12-12:12:12":"1981-12-12-14:12:12"]
plot 'test.csv' using 0:1 with lines

Error:

plot 'test.csv' using 0:1 with lines
                                    ^
"kuehl.plot", line 5: all points y value undefined!

Gnuplot start counting columns at 1, so you must use

plot 'test.csv' using 1:2 with lines

BTW: column 0 isn't an error because it gives you the current row number. So it only gives you the wrong range.
