The null date is only used by formulas, so the description in the current draft should be enough. > <table:null-date> definition > ---------------------------- > > Key: OFFICE-1505 > URL: http://tools.oasis-open.org/issues/browse/OFFICE-1505 > Project: OASIS Open Document Format for Office Applications (OpenDocument) TC > Issue Type: Bug > Components: OpenFormula > Affects Versions: ODF 1.2 > Reporter: Andreas Guelzow > Assignee: Eike Rathke > Priority: Minor > Fix For: ODF 1.2 > > > The <table:null-date> element by itself may not uniquely identify the "date->numerical number" conversion for dates after 1900/3/1. This is due to the fact that some applications have an extra step from 1900/2/28 to 1900/3/1. The OpenFormula draft suggests that documents misrepresent the <table:null-date> so that calculations after 1900/3/1 are correct. This is an unnecessary contradiction between the definition of <table:null-date> and the OpenFormula date description. > A close related omission is that hte standard does not specify how the numerical values change as the date changes. (It is assumed in general that this is linear with slope 1 but the standard fails to specify this.) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
