Game Time v. Real time

So whats the differnce? The overtuned tank armor states that the wear time is 48 hours (in game). Does this mean that I have 48 hours (in real time) before this wears off? Or is there a time conversion that I don't know about? For instance, the day/night cycle in the game appears to be around 1 hour.

It means 48 hours of RL time you spend logged into the game.

So, if you on average spend 2 hours a day logged in..the armour will last you 24 days..

If you keep your char logged in 24 hourts a day, as some do..then it only lasts 2 days.. 48 hours.
