All data is logged as "GMT/UTC" time (that has an offset of 0 hours). If you want your data logs to be adjusted to your local time, you can change the timezone on your Profile settings.
Under the Profile tab, there is an "Edit Profile" link where you can set your local timezone.
Let us know if it's accurate for where you are located. We have users every in the world, so we want to make sure we got it right for all of the timezones.
Thanks!
