That can just happen in chat.
Guild Wars 1 would give you a message every hour 'You've been playing for 1 hour, please take a break' or 2 hours, etc. Don't need a fancy instance timer for that really.
Or (even better) you look at what time it is when you log in (I have my local time displayed above the minimap).
