Hi,
I've just entered 11 notes from Spain, local time 23:10 (CEST == GMT+2). In my list of notes, they appear with my local time as expected. But if I go to the note statistics, I happen to have 11 notes entered in May 2010. I suspect these 11 are the ones I just entered, and appear in May because some glitch in the time zone management by the application.
It's a pity, it would be my best day if these 11 were counted together with other 11 I had entered during the day

.
Edit: in the rankings, I have 11 notes "yesterday" (actually today April 30th!) and other 11 "today". The small letter at the bottom says "cached (last update: Fri Apr 30, 23:23:47, next update in 3 minutes)". So it's April 30th for some things, and May 1st for some other
