Strange behaviour of ISOdatetime

My guess is that your two machines have different setting for locale.  
What does this produce on each of them:

sessionInfo()$locale

(Note: It would have been part of the information that you were asked  
to provide per the posting guide.)

For questions about unexpected behavior or a possible bug, you should,  
at a minimum, copy and paste the output from sessionInfo() into your  
message. When mentioning version numbers, always use the full version  
number, e.g., `2.6.1', not just `2.6', and also mention the platform  
(Windows, Linux, MacOS X, with their versions). Other potentially  
relevant details include the locale (type Sys.getlocale() at the R  
prompt), and whether you installed a pre-compiled binary version of R  
or compiled it yourself.

Hi All,

I am watching a strange behaviour of ISOdatetime. In my work  
computer, I get NA when I try to do

ISOdatetime(1995,03,26,2,0,0)

[1] NA

But on other dates and/or times (hour) works OK

ISOdatetime(1995,03,25,2,0,0)

[1] "1995-03-25 02:00:00 GMT"

In my home computer, I do not have this problem.
I am running the same version of R (2.8.1 patched) on both machines,  
the same version of Gnu Emacs (22.3.1) and the same version of ESS  
(5.3.10). Both are running Windows XP. Has anyone experienced this  
before?
