[R] strptime - %p format doesn't seem to be working

Hi there,

Am I missing something? The "%p" format, which should match against 
AM/PM,  seems to be broken in R 2.3.1 running on Windows XP SP2. For 
example, the following fails

 > strptime("10AM", "%I%p")
[1] NA


whereas the this works as you would expect, but is ambiguous
 > strptime("10", "%I")
[1] "2006-11-30 10:00:00"

Does this error reproduce on other machines, or is it something wrong 
with my setup?

Cheers,



Edward
