Hello, I'm Jc3s5h. I noticed that you added or changed content in an article, 12-hour clock, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Jc3s5h (talk) 15:07, 26 February 2021 (UTC)
