Today's Qlikview "You gotta be f*ckin kidding me" moment
-
Dates. A date is represented as either a floating point value or "datetime". So far so good. I set the date to 0, and the resulting datetime representation was null. Hmmmm. I set it to 1, and the datetime was 31 Dec 1899. Well, okay... I guess. The real adventure starts when you try to find the absolute max datetime that can be represented. There is no documentation that I could find that says what this value is, and I think I know why. That value is 313740917827896, or 31 Dec 4294967295. If you add 1 to the numeric value, the represented datetime becomes 01 Jan 0000. If you continue adding, you can go all the way to 313740918558381, which gives you a datetime of 31 Dec 1999. If you add 1 to that value, it finally overflows into something that evidently cannot be interpreted as a date. If you really want a laugh, I changed that absolute max value to a negative number, and I got a datetime of 4294967292 Jan 1900. Yes, that first number is the DAY. Curiously, it's almost the same value as the max possible year (before it wraps around). I don't know whether to laugh or cry...

She probably was used to MM/dd/yyyy and didn't want to confuse you even more :)

No it's not, why start with a number that only changes once in a millenium? The least you could do is stick that somewhere in the middle! Start with the day, however, and you'll probably never have to read past the first two digits :)

What do you get when you cross a joke with a rhetorical question? The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism. Do questions with multiple question marks annoy you???

I obviously dodged a bullet when I delegated that particular load if crap to another developer.

Because its sortable as text. That's basically the whole point with making it THE standard. ISO 8601 - Wikipedia[^]

Real men sort on substrings! ;p And the really very manly men sort Wendelius' format :~

I don't understand why you're so in love with numbers. Nothing beats localized text so better to use "dddd d MMMM yy". It's just so readable and drops the unnecessary century. We're all at the same millennia here, right? :)
Great idea, that is now the default format in all my applications :D

That format is the most sortable.

I'm not sure how something in C# is applicable to the sh|t stain we all know as Qlikview.

Qlikview is a stand-alone app with no support for plug-ins, or even real coding talent, although it requires one to be able to figure out workarounds for their arbitrary restrictions, numerous limitations, and bugs that they prefer to call "nuances". As a programmer, Qlikview's "programming" features are an affront to my developer sensibilities. If anyone on the planet was in danger of having physical harm inflicted on them from a carefully aimed shot, it's the sub-humans that invented Qlikview.
