Doh, I tried hovering over it for the actual date before, but I obviously didn’t hover long enough! For other readers, just hover over the “a year ago” for the actual date. Just make sure you don’t get too impatient like I did
FWIW though, it says “a year ago” when it was 17 months. I think just defaulting to showing the actual date would be more helpful, given the target audience of these pages. I know Github does it, I find it unhelpful there too! This is a very minor criticism of an otherwise great service, just in case I’m coming across as grumpy!
