I think we should change the data in this test so it passes
Also, it looks like a slight regression to me in that parsing 2021-1-1 used to parse and now doesn't.
So I suggest:
1. Change this test from
2021-1-1T05:11:10.432
to something like
2021-01-01T05:11:10.432
2 file an upstream ticket in arrow-rs to be more lenient
Aka to accept 2021-1-1T05:11:10.432 as valid -- I can do this if you like

- Change this test from
Will do
2 file an upstream ticket in arrow-rs to be more lenient
I would strongly request we do not do this, it will severely hurt performance for an incredibly esoteric use-case. It isn't actually documented that chrono supports this, and we have never intentionally supported it either

Arrow no longer supports timestamps of this shortened form, it has never been documented to support them, and it is an accidental undocumented quirk of chrono that it did. I would very strongly resist changing this, being able to predict the digit locations ahead of time is critical to avoiding a data dependency when parsing.

Filed apache/arrow-rs#3969 to track (I don't think we necessarily need to change arrow to support these timestamps, it but it will reduce confusion to have the change documented)
