I don't know if anyone has suggested this or if there is another way that I am simply missing, but when I want to check when other players have played I have to do mental calculations to convert it to my time. If there was a running game clock of simply the time of day I could just see that a player had just played x hours ago and it would be easier and faster.
I know it's not that hard to figure out the time, but I think it would be better with a clock.
