Hi there.
Not sure what happened, if this is something normal, possible, or if someone is copying your website without consent here, I just wanted to warn just in case.
I typed "mysql date format" on Google today, and I clicked on the first result, which was a featured snippet (that Google thing that shows part of the page's content that might be what you're looking for). I didn't check the website. Then I landed on a page that looked almost identical to w3school, but it's not, and this is what I found weird.
Here's the link to the webpage: http://www-db.deis.unibo.it/courses/TW/DOCS/w3schools/sql/func_date_format.asp.html
And just a screenshot of the search result on Google as of today:
Is it normal? Is it a safe website?
Thanks by advance!
