Great!
Now you have communicated a solid idea of what you want the end result to be like.

Now. . . .

We try to figure out how to do it.

The first path I think I would examine . . . .
The K2 isn't known for its processor power or vast realms of RAM.....

Once every minute, wake up -
Ensure nothing else can write to the screen -
Get current time (from the Kindle, and once every xyz times, from the NTP network - adjust Kindle time as required) -
Both are text replies -
Format text as required, write directly to the frame buffer, trigger a screen update (which might make it flash once a minute - we will just have to see about that) -
Refine as required.

I think the "Kindle as a weather display" (the one without a local server, only a network source) works like that.
I recall twobob building the rendering programs for that project.

Find, and review that entire project thread.
Maybe we can re-use most of what they found for the K2 (I think that was for either the K4 or the K5).
