Re: Date formats

In Paraguay, as in most of the civilized world, we use ddmmyyyy separarted either by /, -, or .
Is is not practical for sorting, but using "date" fields the order comes out Ok.

But, as any other rule, there are exceptions, and now I have a task for which I need to sort using mmddyyyy, to list aniversarys. For each month: the list of days, and for each day the list ordered by year.

Date sorting is most 'natural' when done yyyymmdd. That is why people always want to switch the order of the parts. This is actually quite mute in anything that is done with native date values, but most databases on the i are not set up this way. From what I've seem most date records are stored as numeric, and I'm guessing 8,0 numeric at that. If everything was stored as Date then there would be little use for all this switching around since I'm not aware of too many people who display dates as 2009/12/16, or 2009, Dec 16.

I wonder... if native date support had been in place since the beginning, would we have ever seen the 10000.01 trick? I'm only coming up on my 3rd anniversary on the platform, so this might be a naive point of view.

If you use numeric fields for your dates I think mmddyy has a more
'natural' sort then ddmmyy. Of course, being from the US, I'm biased. :)

Or is there another reason for this format?

When I was working on IBM's Y2K offerings the contractor that produced

the

tool did not originally include an MDY version as they had never

heard of it. As a result (and luckily for them) they had never

encountered the idiotic multiply by 10000.01 conversion method either.
