Most likely duplicate of #49028, which has been fixed in #49130, but if my timezone math is correct, the mentioned failure happened after the merge of that PR, which I don't understand. Let's watch for a while if it happens again, and close if it doesn't.

Triage: this should be already fixed. We need to check Kusto data.
