Is TimeZoneOffset broken?


I just realized that code like this:

TimeZoneOffset[Entity["City",{"SaoPaulo","SaoPaulo","Brazil"}],0,{2020,1,1}] 

does not return a timezone value anymore. I am quite confident that this has worked up to a few days as I run test-code which contains that snippet (almost) every night.

Similar code is part of the documentation and has been suggested on this site, e.g.:

TimeZoneOffset[Entity["City", {"Paris", "IleDeFrance", "France"}]] TimeZoneOffset[GeoPosition[Entity["ZIPCode", "94402"]["Coordinates"]]] 

and those examples also don’t work for me anymore. Interesting thing is that this is independent of the mathematica-version I use and happens on at least three different machines that I have access to. Does anyone else see these problems except for me? I would consider this a bug…
