This is because format.dates has become non-callable from outside the chron
package. Until the next release of Hmisc you can download a fixed version of
the describe function at

The Hmisc function describe fails, giving the error message:
Error in formatDateTime(dd, atx, !timeUsed) :
could not find function "format.dates"
Loading the chron package, where function dates apparently resides, does not
fix the problem. Note also that loading chron gives a warning. Earlier
versions of chron from the archive failed to load properly. Please see the
entire session below, with the error message at the bottom.
Thanks.
