Simple clock in one of the corners (Prob best in the classic bot left, right cozy underneath the replay speed)

Also probably an option between military time and AM/PM. Simple, ez, biggest help

Couldn't you just use a Lua script for this

XD

The problem I see with that reality is time zones and the location cannot be set by the player. The forums set it for you and is generally not right or doesn't work anyways. Of course you could make it so you set time zone in game, but steam version is better than stand alone anyways. More reliable, and updates easier/more often.
