Re: QCENTURY and other date-related system values

Just guessing here but since this is the SYSTEM time I'm guessing someone decided there was no possible computer before 1928 or some similar thinking. Perhaps 1928 was an important year in computing?

As to 2053 maybe IBM is saying that i 7.3 support will really truly end in 2053 as you won't be able to set the date beyond that year! Time to upgrade!

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.
