Dear Ola,

I think you spotted a small bug in *package* fCalendar.
Explicit specification should prevent "autodetection" of the date 
format, which is not the case for fCalendar v251.70, instead 
autodetection is done at least once (twice, if actually appropriate).
With the following patch, things should work ok:

diff --recursive fCalendar.orig/R/3A-TimeDateClass.R 
<     charvec = format(strptime(charvec, .whichFormat(charvec)), isoFormat)
 >     charvec = format(strptime(charvec, format), isoFormat)

You did not provide the output of sessionInfo() (which you are asked for 
in the posting guide). If you are using Windows and don't know how to 
apply the patch, you can download a patched binary version here:



PS: Maybe r-sig-finance is more appropriate for questions concerning
