It is also supposed to be easy to understand
So, when it says 99:99 it is "easy to understand that it is 6 days and 3 Hrs? No it is not.
to nicely fit into the box where it is displayed.
It can feet easily. There are two characters and separator in the box, so even w/o changing the box size (although there is no reason why it should stay the same size), you can write - 6D:3H.
we should believe it follows the design choice made by the developers (given how visible it is they otherwise would have figured that the clock is wrong and fixed it by now). A bug it is not.
It does NOT show the
correct time!!! This is a bug! It does not matter where the bug is. The customer see a clock and it is not accurate => bug in the product.
I have clocks that show the time correctly two times a day (figure how). Isn't it an "HW" bug? Yes it is most definitely is.
It is not a critical or a hard bug, and it almost redundant, but a bug it is.
