When parsing a pst file from the enron data set I get an email created date of May 2009 from the OutlookPSTParser for all emails. Looking at the underlying PSTMessage coming up from libpst I can see that the createdDate field has indeed got that value - I'm not sure where that date is coming from, but the Enron data set was released in 2002.
I can see that the pst message has the correct date value in the clientSubmitTime field.
getClientSubmitTime() is not used when setting metadata in the OutlookPSTParser.
Can the result of this call be added to the metadata?
