Very easy to do, it should only take a few minutes.
[Edit]
Here replace your Window_PlayTime script with this, or put this above main.
#==============================================================================
# ** Window_PlayTime

class Window_PlayTime < Window_Base

# * Object Initialization

def initialize
super(0, 0, 160, 96)
self.contents = Bitmap.new(width - 32, height - 32)
refresh
end
#--------------------------------------------------------------------------
# * Refresh

def refresh
self.contents.clear
self.contents.font.color = system_color
self.contents.draw_text(4, 0, 120, 32, "Location")
map = load_data("Data/MapInfos.rxdata")
self.contents.font.color = normal_color
self.contents.draw_text (4, 32, 120, 32, map[$game_map.map_id].name, 2)
end
end
