The date shown on mouseover of the rating graph on the profile on the website is wrong, showing rating changes as one day before the real rating changes (i.e. showing things which occurred on Oct. 29 as if they happened on Oct. 28). The "activity" feed just below it as well as the rating graph on the mobile app show the correct dates (as reckoned by the server in France).
This bug was not present last week.
@agentCardboard
that's not a bug. beacuse lichess uses UTC time.
but it is still inconsistent with the activity feed and the mobile app. (Though I had misjudged which exact time zone the site uses.)
o.O
