Logs uploading inaccurately


So everytime I upload my logs from wow, the dps of every single person in the raid is bumped up about 200-300k more than the people actually pulled on the fight according to details or other peoples logs. This didnt happen to me back in nighthold, but sometime in tomb it changed and has been that way ever since. For example last night I had a 2.04m parse on heroic garothi in Antorus, but when I upload the log, it says I did 2.35m. Any ideas whats causing this and how to fix it?


Is your system clock broken and accelerating time?
