Not an accessibility or html expert, but in the AWS console you can switch between "x days ago" and exact timestamp by clicking/tapping the timestamp.

Not an a11y expert but I imagine that's what the <time> element[1] is for.

I've been developing my new website and use "x days ago" which is a feature of most date libraries like luxon or moment. I modeled what GitHub does where you can mouse over the text and it produces the actual timestamp. On mobile that doesn't work, so I print the date in disabled text.
