I have a similar issue. You have a great site and very helpful. Discovered it while researching an intermittent wireless slowdown, which appears now to be from my ISP. I am running some long term tests on my desktop to begin a discussion with them, but the time in my logs show test times two hours earlier than actual. My detected information is correct (Alabama, Central Time) and most of the tests appear to reflect Dallas (also CDT). Any suggestions?
