Profile graph dates out of phase by 1 day

I would like to point out that when I click on my profile and run the mouse pointer over the graph, the dates are one day off. For instance, my rating today May 10th for classical chess went up to 2111. The graph shows it updated to that rating on May 9th. Also I became a member on May 7th but the graph shows a start date of May 6th.
Maybe the dates are related to UTC or another timezone different from yours.
