R help - Nov 2006 - Convert ordinary dates into POSIX

Does anyone know where I can find any tool for Windows that converts
dates from ordinary formats into POSIX?
I need it to import sime time series from Excel into R and use them
with its package.

Thanks!

?strptime in R.

However, if you want to convert dates (and not date-times), see ?as.Date, 
using the 'format' argument.

RODBC is able to do so automagically in most cases (at least in English 
locales).
