Hi Michael,
Perhaps this will get you out of trouble.

mmdat<-data.frame(time=paste(c(14:23,0:13),"00",sep=":"),
 wind_speed=sample(0:30,24))
plot(mmdat$wind_speed,type="b",xaxt="n",xlab="Time")
axis(1,at=1:24,labels=mmdat$time)

If you want to get more tick labels on the time axis, look at staxlab 
(plotrix).
