Pretty much since forever.  The documentation just never picked up on 
the axis argument to 'set timefmt'.  You get a hint that something might 
be afoot if you inspect the timefmt:

gnuplot> set xdata time
gnuplot> show timefmt

         read format for time on x axis is "%d/%m/%y,%H:%M"
         read format for time on t axis is "%d/%m/%y,%H:%M"
         read format for time on u axis is "%d/%m/%y,%H:%M"

gnuplot> set ydata time
gnuplot> show timefmt

         read format for time on y axis is "%d/%m/%y,%H:%M"
         read format for time on x axis is "%d/%m/%y,%H:%M"
         read format for time on t axis is "%d/%m/%y,%H:%M"
         read format for time on u axis is "%d/%m/%y,%H:%M"
         read format for time on v axis is "%d/%m/%y,%H:%M"

There would be no point showing so many timefmt strings if not at least 
some of them were independent...
