Historian Quality code 1073742080 - What is it?

When history values are requested for intervals in the future, an undocumented quality code is shown. (At least, I can't find documentation of it)

Does anyone else get the same code?

I think it's just Uncertain with no additional sub-code or info.

It is 0x40000100. So, "uncertain" with subcode 256. Sounds familiar, but I don't recall from where. /:

Yeah, 256 is the code for Uncertain, and the high bits are the Uncertain severity.

It's Uncertain/Uncertain.

/**
 * An unspecified degree of uncertainty exists in this value. Good luck!
 */
public static final QualityCode Uncertain = q(Level.Uncertain.code(256));

lol
