From: dewar@gnat.com (Robert Dewar) To: dewar@gnat.com, jsm28@cam.ac.uk Cc: clock@atrey.karlin.mff.cuni.cz, gcc-gnats@gcc.gnu.org, gcc@gcc.gnu.org, geoffk@geoffk.org Subject: Re: c/3190 Re: warning: `%y' yields only last 2 digits of year Date: Tue, 12 Mar 2002 18:06:33 -0500 (EST) <<That date has six possible interpretations (the order of preference between them being culturally dependent). Unless you have some arrangement as to the interpretation of such dates with anyone who might read them, they hardly seem like a good idea to write - certainly, when such dates appear on web pages, they generally are confusing and it's a matter of second-guessing the intent of the writer. I'd always use yyyy-mm-dd (ISO 8601 format) in such a case, given a free-format date field. >> Wait a moment, you are obfuscating with irrelevancy here :-) I *specifically* talked about the date on a check (and given the spelling, I had in mind a US check, and not a british cheque). The interpretation of the date is quite unambiguous here, and I definitely do NOT suggest thgat you try to use the ISO format in that context. Actually I prefer in more general contexts to write something like Mar 16 '02 which is clear to all (of course in those very rare contexts where the century is not clear from context it is OK to use 2002). But all this irrelevant discussion has nothing to do with the warning. %y is a perfectly well defined, and useful function. it is reasonable to assume that anyone using this function knows what it does and means to use it. By the way, I have often filled out goverment forms that allowed precisely two digits for the year :-)
