Another undiscussed mechanical edit? Please stop making these - someone will just have to revert it.

It is a handmade edit. But something went wrong with level 0 and all items that were loaded had a there version updated even when I didn’t edit them. What was being done was: searching for errors with a text editor and then fixing them. Sorry it looks bad

I'm guessing that the "unexpected change" at http://osm.mapki.com/history/way.php?id=364690421 was to trim trailing spaces on tags?

Also what was the source for the "and then fixing them"? It can't have been Mapbox Satellite.

first i'd like to decaire some other changesets of my with the same caractioristics.

What I did is I downloaded the UK form geofabrick and then filleted all nodes ways and relations that have opening hours.
This results in a 50 mb file that covers all of the UK and has only things with opening hours. That I load in to josm and I validate all things using the build in validator and then I fix some stuff.
Like I look at the opening hours stated and I write them in the syntax that we all agreed on. I also follow some recommended changes that josm provides. Like trimming spaces at the end of properties and values.
Lastly there are some values for openings hours that josm can’t parse the openings hours and it doesn’t have a fix for it. Those I write to a smaller osm file and put in to level 0. From there I paste the generated text in to my favorite text editor and then I search for things I can change so that josm can read them. For example I search for “0800” and change that to “08:00” so that josm understands it again. And those changes I upload again and then validate them again and fix them.
And for the source it is something that was already in the change set and I forgot to remove it. The only source that I use is osm and the website of the company if I can’t read the openings hours.
So I like to think that the change sets fall in the category of handmade mechanical edits. I let the machine look for the errors and I fix them.

Thanks for the detailed explanation. Were there any examples of "opening hours set to something that makes no sense, but would make sense if applied to another key"? Were you able to figure out what do do in those cases, or did you add an OSM note or ask the previous mapper?
For a comparison, I recently did something similar with "no=yes" tag/value pairs - even with something as common as that, it was often possible to guess the thing that should have been set to "yes".

i mostly ignored it and did somthing else but i also could add a note.
