is this supposed to work for dates before the epoch or the Gregorian calendar cutoff?
maybe you can add tests for these too - if they are not supposed to work, the errors can be tested.

So the mechanism going from millis->timestamp String actually lives in DateTimeUtils in Avatica and is pretty well-tested in DateTimeUtilsTest (let me know if you need links.) The real bug here is that JSON doesn't distinguish the numeric types so we have to ensure it's a Long (or convert) it. So that's the scope I'm trying to test here.

I have approved, I leave to you this decision.

not easy to check that this value corresponds to the date below.

Yeah I also wasn't sure about this.. the point I was trying to illustrate is that one case is below Integer.MAX_VALUE and the other is above, any suggestions?

putting this in a comment will help a bit - the purpose of this choice is clearer
but if you have validated this using other external means, like another DB, you can also mention it in a comment.

@mihaibudiu have you seen the Windows failures like the ones on this PR before? They look unrelated but thought I'd ask? |

I have seen similar errors in windows builds, but not this many... they usually go away if you rerun the failed jobs. |
