There seems to be an issue of how some1900 dates are being stored in the OpenOffice spreadsheet.
It is my understanding that dates are stored with spreadsheet as a serial number starting with 01/01/1900 being stored as a '1'. When 01/01/1900 is looked at as a general number format in OpenOffice it appears as '2' versus a '1'. When 02/01/1900 is looked at as a general number format in OpenOffice is appears as '33' versus '32'. When 12/31/1900 is looked at as a general number format in OpenOffice it appears as '366' which would be correct since 1900 is a leap year. 12/31/1900 is the stored as the correct serial number because 02/29/1900 is not considered a valid date in OpenOffice and therefore 03/01/1900 is stored as a '61' which is correct and the following dates are stored correct for 1900. Will look at other years which are leap years to see if similar problem exists.
