GNOME Bugzilla – Bug 113845
date format for pre-1900 dates
Last modified: 2008-04-11 23:11:38 UTC
Gnumeric does not properly format dates that occur before 1900. Enter a date such as 3/20/1900 -- Gnumeric recognizes this as a date and formats it properly. Enter 3/20/1899 and Gnumeric represents this as a text string. Changing the format to date -- either before or after entering the date -- has no effect on pre-1900 dates. I removed my default Redhat RPMs that were outdated and upgraded to gal-0.24, guile-1.6.4, and gnumeric-1.0.13. The bug is still present in this version.
Its not so much a bug as a design limitation of MS excel. Dates are stored as 'days since jan 1 1900'. It may be feasible to work around it with negatives, but definitely not in 1.0.x.
Substantial work on this bug has occurred over in bug 509720. *** This bug has been marked as a duplicate of 509720 ***
