Two digit years have always been a problem. I always presume that the use two digit years was obsolete after the Y2K publicity, but bad habits continue. We are no longer in the era of eighty column punch cards, so there is no excuse for two digit years. ISO8601 is the international standard, so it is not ambiguous. In other formats, using four digit years and month names are not ambiguous no matter the element order. Any other formats require a time consuming examination for clues as to element order or an explanation from the source. My input data may be in any of the formats. Once I determine the order of the elements and resolved two digit years, I can easily convert to ISO8601. -- View this message in context: http://nabble.documentfoundation.org/Date-will-not-format-or-sort-when-imported-into-calc-ods-tp4004907p4006914.html Sent from the Users mailing list archive at Nabble.com. -- For unsubscribe instructions e-mail to: users+help@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
