My characters were deleted?

[ride the spiral]

Hmm, not sure if this is of concern or if this is a glitch. Several of my characters have more days played that I remember playing them. For example my 14 bard has 34 days played, and my level 20 warrior has 125 days played. I definitely did not spend that much time on those toons, nor did I sit and afk with them. My main, has 2610 days played ........ lol thats impossible.

Is this a known glitch or cause for concern (maybe my account was hacked and people had logged in on my toons). I don't seem to be missing anything, have all my plat, my lower level toons are still twinked out with things like FBSS, etc.
