How long exactly is rep mode?

jesus its felt like ive been playing this server for multiple hours and yet i still cant register. is there any command that allows you to see your exact playtime? it would be great to know.
and also i know that you have to be playing the server and not standing in /rift. ive been playing the pve mode and killing bosses

roughly somewhere in 2/3/4 hrs you get 4 hrs if you are unlucky
