plot.zoo warnings - ignore or look for problem?

I'm getting warnings when I plot a zoo object:
dts <- chron(rep("2007-09-10", 5), paste("00:0", 0:4, ":00", sep=""),
c("y-m-d", "h:m:s"))
dat.zoo <- zoo(1:5, dts)
plot(dat.zoo)
Warning messages:
1: In v[[perm[1]]] : partial match of 'm' to 'month'
2: In v[[perm[2]]] : partial match of 'd' to 'day'

The plot appears to be correct.

So, is this a warning I can ignore, or do I have something amiss?

I have v 1.4-2 of zoo, built for R v 2.7.0, but it doesn't say it
requires that version of R.
(I realize I am not up-to-date on the version, but running production
apps sometimes means we have to wait a bit to upgrade.)

I am unable to replicate that.  I don't get any warnings.  Perhaps
they are coming from chron and you have an old version of chron.
Try upgrading chron to the latest version (2.3-22) and try it again.

That did it, Gabor.
Thanks! I didn't think chron would be involved.
