I just upgraded from LibreOffice 3.6 to 4.4, in Ubuntu Linux 12.04. Now when I type a date, Calc does not accept it as a date. In the older version, I could type “4mar” and then as soon as I clicked Enter, in the cell would appear “04-Mar-15” (assuming that’s how I’ve formatted that cell). Now, in the cell I just see “4mar”. As far as I can tell, the program has kept all the same settings as before. How do I fix this problem, or get around it?
