Incorrect Skill training time in game

I like to use the in game incomplete skills icon that shows up when fitting to find out how long I have. I just noticed today though that when comparing it to EVEMON the times are quite off. I think it’s a bug because I bought skills on one character and the time did decrease even in the fitting window, but not until I had it in my training queue.
This character isn’t remapped and doesn’t have implants in, so I’m not sure why this would be the case.
