What language and locale are you in? BR Portuguese?

I'm just using US English and here's what I see on iPhone XR with iOS 12.1:

It really looks like this could be a Safari bug related to your specific locale.

Actually, this also looks like it could be an issue with Brazil DST: https://www.timeanddate.com/news/time/brazil-postpones-dst-2018.html

First it says

The Brazilian authorities have moved the beginning of Daylight Saving Time (DST) from November 4 to November 18, 2018 to avoid interference with a nationwide university exam.

Then

Update: DST Not Postponed after All

The Brazilian authorities announced on October 15, 2018 that the beginning of Daylight Saving Time (DST) will not be postponed after all. Clocks will be advanced by 1 hour at 00:00 (12:00 midnight) on November 4, 2018, as previously planned.

I got this from this SO answer which was indicating that

so local dates at Oct-21-2012 between 0:0 and 1:0 doesn't exist in Brazil!

Which might be an issue again with 2018's DST.

This issue was fixed in Chromium in 2014.
But it is still an open bug for Safari. You can track it here.
