International Date formats

Does anyone have a suggestion for being able to store "dates" parsed
from email headers that would handle a fairly international set of
formats?  Or do I need to do date-conversion prior to trying to store?

currently choking on things like "Ene-18-2007" (Enero = January) and
"Sau-20-2007" or "Oca-29-2007" or (I have no idea what "Sau" or "Oca"
are) and we especially don't seem to like dates that my 7-bit Windows
window calls things like:  "╤│≈-11-2007"
