Plots using POSIX

Is there a reason that the bottom axis changes color when POSIX data is used in plot function?
It's not the same plot function, that's why.
For example:
timedata <- c("2/3/2003","3/4/2003","5/4/2003")
timedata2 <- strptime(timedata,format="%m/%d/%Y")
numdata <- c(2,3,4)
plot(as.POSIXct(timedata2),numdata,col="red",type="o")
As compared to:
numdata2 <- c(3,4,5) plot(numdata2,numdata,col="red",type="o")
I assume that the work around is to place the box and axis after the plot is created, correct?
Or the lines after the plot is created.
plot(as.POSIXct(timedata2),numdata,type="n") lines(as.POSIXct(timedata2),numdata,col="blue",type="o")
