A: What does the column "created" in the list of tag synonyms mean?

reneIt is what the label promises, the creationdate of the synonym and that is the date the synonym got proposed. Here is how I reach that conclusion: Lets look at the list, specially the synonym for total-reputation. I picked that one because it was created by a non-diamond. Now look at this S...

I should have thought of possibility to check this with SEDE.
Actually, while you were writing the answer, I was working on a SEDE query at the same time - I created a query for all synonyms and also for one specific synonym.
I guess it is a bit similar to your query - perhaps the main difference is that you are checking only the approved synonyms; by using where approvaldate is not null.
 
yeah, I was trying to gather all data points I would need in one go
is my answer still useful or were you looking for something different as you seem to want to rule out SEDE?
 
I am fine with the answer.
The possibility of trying SEDE occurred to me only after I posted the question.
I find it unlikely that there is also some way to find the approval date through the UI. (The most logical place would be the list of tag synonyms and it's not there.)
But leaving the question whether there is also some other way probably does no harm.
I'll wait a few days before accepting the answer - but I don't think there is something substantial to add.
 
The tag dashboard is new-ish: meta.stackexchange.com/questions/329687/…
I might as well wait for Adam Lear to come by and confirm my analysis is correct. Maybe there is some caveat I didn't overthink. I don't use that page fairly often.
 
I stumbled upon this because somebody asked question along the lines: "Why this tag disappears when I enter it?"
The user who asked this question also said that they remember it was a separate tag. Since I thought that this column shows when the tag was approved, I originally claimed that the synonym has been three since 2016.
