This morning I had another look at this problem and I noticed something I missed yesterday.
My spreadsheet contains a line which I use as a kind of template. This line contains the formula like =Annn in column B and =Ennn-Dnnn in column F (typo here in original report). In all cases nnn is the number of the current row. Whenever I insert a new row into the spreadsheet I copy this template row into it. What I missed when writing my original report is that in the template row and its copy the row number had for mysterious reasons gone bad by ten. After changing this back to the correct row number the date and the time difference display correctly. My apologies for this noise. However, the problem mentioned in the subject of this report still stands: Format Friday is no longer available for Category Date in the list presented by CTRL+1 for a newly created .ods file. It is available in the older file. Regards, Jeroen. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
