Does the "OpenOffice v2 dump" convert the date correctly when
exporting into PostgreSQL?

The date in .xls when using excel is exported to CSV as a number
which is tricky to convert to a date. This is what I use :

date_pli('epoch'::date, date_num::integer - 25569) AS date_fmt

The number "25569" is a fudge factor, that can be different between
dumps, but stays consistent through the dump. I usually adjust it
and compare the result to the value shown in excel until I get a
match.
