Any idea what's going on with this? Running strptime against all dates
from around 1946, only 5/3/1992 was converted as NA. Even stranger,
it still seems to have a value associated with it

I can't reproduce your problem on R 2.13.0 on linux:
strptime(5/2/1992, format=%m/%d/%Y)

For what it's worth, I cannot reproduce this problem under a nearly
identical instance of R (R 2.12.1, Win 7 Pro 64-bit). I also can't
reproduce the problem with R 2.13.0. You've got something truly weird
going on with your particular instance of R.

Hi Bill,
Thanks for your reply. The results look almost identical to my eyes,
except for the mysterious TRUE...
