The problem is that dates in spreadsheets are stored as days from some date. For
a more complete answer see:
http://www.lexicon.net/sjmachin/xlrd.html

On the above page is a link to the OO documentation for spreadsheets. The trick
is to copy the formatted date not the underlying value. I know I have done that
in the past but at this point in time I cannot remember how. You might want to
Google OO base spreadsheet date conversion or something similar.

I remember now. I exported the data as a csv file and then loaded into Postgres.
The export converts the dates to strings representing their formatted values
not the underling integer.

Somebody should file a bug/RFE against OpenOffice, suggesting that there
ought to be an option to store dates as dates when storing into SQL
databases.

Once the column is formatted as "Date" the underlying value will be the integer value. I did a little test and found
thefollowing. If I preformatted a column as "Text" and then entered date strings for example "12/01/09" it stayed a
stringwhen cut and pasted. If I just started entering a date string in a column the column would become a "Date"
column.Changing the formatting to "Text" would change the date strings "12/01/09" to the underlying integer 40147. Any
newdate strings entered however would stay as "12/01/09". Hope this helps.

Might be easier to use the CREATE TABLE AS command:
