I have changed my timezone numerous times and in my individual blog entries the time is correct. I can even schedule a post and it will appear at the correct time. However, when I check my stats, the time is still on the UTC (I’m in Indiana, UTC-4) and therefore the number of hits per day are incorrect because 4 hours of the current day are being placed with the next day’s numbers.
(Example: Right now it’s May 20th. I can post and the date will say May 20th, but my stats are already counting for May 21st.)
