Re: QCENTURY and other date-related system values

False. The system values are NOT all *settable*.

WRKSYSVAL QUTCOFFSET
2=Change
System value QUTCOFFSET cannot be changed.

But maybe you were meaning to say these system values are *settable*:
WRKSYSVAL *DATTIM
Well, most of them. Including QDATETIME
Thought about changing that on our sandbox lpar but I think I would want
to only do that in restricted state so as not to screw up any logs and
journals.

Well, the system values are all *settable*, not just gettable. So
let's say you set QDATETIME to 4018-06-28. What do you get when you
retrieve QDATE and QCENTURY?

Obviously, I'm not going to try this on any actual machine!

More to the point, any date data type with a
4-digit year will correctly support any year up to 9999. The 54-99 and
00-24 century crap only applies if you are using date data types with a
2-digit year.

I wouldn't be so sure. Why does the documentation say that the years
1928 through 2053 are supported? Why not a 100-year window? Why not
1901 through 2099?

There are sometimes other constraints besides the number of base-10
digits. I don't know if that's the case here, but I don't know that
it's not.
