I added a contact to my address book who was born on 1952. The short date on my system is set to show only 2 digits for the year. When I open Kontact, in the Summary it shows that there are a few days left for my contact's birthday to come and that it will be more that 4 billion years old on that day. The number is exactly 4294967248 which is the unsigned integer value of the 32 bit 2-complement representation of -48, i.e. 2004-2052, so I suspect the problem is related to a sign issue somewhere. I have no way to post a bug in Internet and I may be wrong in the first place. Have anyone seen a similar behaviour on its system? Could anyone post the bug if so? Thanks in advance. ___________________________________________________ . Account management: https://mail.kde.org/mailman/listinfo/kde. Archives: http://lists.kde.org/.
