That was a different issue (missing minutes and seconds) and in

We don't have the 'at a minimum' information asked for in the posting
guide, but your example works for me on my Windows XP machine. Note
that the use of %p differs by language settings (and I have seen
reports where that was the issue). I used
sessionInfo()

in the Europe/London timezone.

Re: [R] AM/PM strptime %p failing 2.11.0 WinXP
I know it is not very useful to you, but on Vista with 2.11.patched it
works:
> strptime("5/20/2010 6:45:32 PM", "%m/%d/%Y %I:%M:%S %p")
[1] "2010-05-20 18:45:32"

Maybe you can try to set the LANGUAGE to English.
Good luck!
