Anyone know what 'logged in' actually consists of?
I'm showing 588 days. Obviously I've been here for longer than that and I've surely logged in and changed the odd password during the last 588 days so I've never been totally sure what it's actually representing. I certainly never knowingly log out.
That's the total time you have been online.
"Total time logged in: 588 days" does not mean that you've a been a member of bitcointalk for 588 days. It means that the total time you have been online is 588*24 hours.
