Steps to reproduce: 1. Enter a time value that is greater than one day, for example 34:56:12. Alternatively, enter a value greater than 1.0 (for example, 1.2345). 2. To be sure, format the cell to "[HH]:MM:SS". 3. Export the spreadsheet as Excel 2003 XML. 4. Try to load the file into Excel (I've tried Excel 2007). 5. Excel gives an XML error message and rejects the entire file. If one checks the XML file, the following string is exported: <Cell><Data ss:Type="DateTime">1899-12-31T34:56:12.000</Data></Cell> The time part shouldn't exceed 23:59:59.999. The correct data would be: 1900-01-01T10:56:12.000 (this is exactly what Excel exports).

Hi Swante, seems that Excel have a problem with 'negative' dates, Dates before 01.01.1900. So the XSLT may change this tag accordingly. Problem here is this change may have influences on date calculations. Please ask DR for details. Maybe this is a candidate for a wontfix, it's up to you. Frank

Hey, wait a minute! "1899-12-31" is NOT, repeat: NOT a "negative" date. Check an XML file exported by a real Excel. Or simply read MSDN on Windows date types, such as DATE or COleDateTime. I was going to post another error which is based on the same bug in the Excel XML import/export: if I export 0:00:00 from Excel (that is, 1899-12-31T0:00:00.000), this cell is displayed as 24:00:00 in OOo Calc. Anyway, having a date-time with an hour value greater than 24 is surely a bug. Furthermore, generating an XML that does not conform to the referenced schema is also surely a bug. And as we're speaking about Excel's own format, I think one should take Excel as the reference in this matter. So it's NOT Excel that's having a problem.

Thanks for the issue joghurt. Although it is uncertain when I will ever be able to work on this filter again. I really hope than someone of the community is able to provide some patches for this. Marked with keyword 'needhelp'!
