"In-Game" time indicator

Since the internet is a global thing and people could be playing anywhere at any local time of their day, it would be helpful to have an easy way of knowing what time it is in-game. For me, in-game Midnight comes at 4pm.

Yes, I could go Google what time it is in Berlin. But, it would be simpler if there was a small clock in the upper corner of the screen by the user's name, or even above "Winston Churchill" who seems to be constantly prompting me to make allies. Either of those places are pretty much wasted screen space that could be put to good use with a very small digital clock display.

Since so many things change at midnight (newspapers, morale changes, research abilities, etc.), it is something to keep an eye on.
